The Nahua Hidden World Part 2: Mirrors, Plants, Altered States & Death · The Occult Rejects

  Speaker 1: You see, something's going to happen. What?
• 0:09
  Speaker 2: What's going to happen? Something wonderful.
• 0:13
  Speaker 1: What? I understand how you feel. You see, it's all
• 0:18
  Speaker 1: very clear to me now. turns into deliberately changing the
• 0:33
  Speaker 1: conditions under which that hidden world might appear. In Part 1,
• 0:38
  Speaker 1: we established the basic architecture. Nahua manuscripts were not simply
• 0:42
  Speaker 1: illustrated books. The Tonopahuali was not simply a calendar. Tonali
• 0:47
  Speaker 1: could connect birth, heat, day, vitality, and destiny. Omens became
• 0:52
  Speaker 1: meaningful through context. Dreams and Ohali traditions complicated the boundaries
• 0:56
  Speaker 1: of personhood. And specialists existed because some forms of hidden
• 1:00
  Speaker 1: information required training to interpret. The pattern underneath all of
• 1:05
  Speaker 1: it was relational. Time, body, dream, place, and event could
• 1:10
  Speaker 1: become readable under particular conditions. Part 2 changes the problem.
• 1:16
  Speaker 1: Instead of asking what happens when a sign appears, we're
• 1:19
  Speaker 1: going to ask what happens when human beings deliberately alter
• 1:22
  Speaker 1: the body and sensory environment in order to make ordinary
• 1:25
  Speaker 1: perception less stable. Darkness can reduce visual certainty. Sleep loss
• 1:30
  Speaker 1: can change attention and perception. Fasting can intensify bodily sensation.
• 1:35
  Speaker 1: Rhythm and repeated vocalization can reorganize attention. Smoke and scent
• 1:39
  Speaker 1: can transform an environment. Pain and bloodletting can make ritual
• 1:44
  Speaker 1: physically unforgettable. Psychoactive plants can alter perception through chemistry. And
• 1:48
  Speaker 1: reflective surfaces can create ambiguity between what the eye receives
• 1:52
  Speaker 1: and what the brain constructs. That brings us to an
• 1:56
  Speaker 1: object almost perfectly designed for this investigation. polished black obsidian.
• 2:01
  Speaker 1: It is volcanic glass made reflective, a surface that can
• 2:04
  Speaker 1: show an image while simultaneously swallowing light. Standing behind that
• 2:08
  Speaker 1: mirror is one of the most complicated divine figures in
• 2:11
  Speaker 1: central Mexican religion. Being associated with rulership, conflict, uncertainty, fate, power, night, sorcery,
• 2:20
  Speaker 1: and supernatural vision. His name is Tezcatlapoca, the smoking mirror.
• 2:26
  Speaker 1: If part one asked how the Nahual read a world
• 2:28
  Speaker 1: full of signs, Part 2 asks something more unsettling. What
• 2:32
  Speaker 1: happens when ritual deliberately changes the conditions of perception until
• 2:36
  Speaker 1: the boundary between seeing and interpreting becomes difficult to locate?
• 2:41
  Speaker 1: Tezcatlapoca is one of those gods who becomes simpler the
• 2:44
  Speaker 1: farther he travels from his own culture. Popular mythology books
• 2:48
  Speaker 1: frequently reduce him to something like an Aztec god of darkness,
• 2:52
  Speaker 1: while modern occult writing sometimes turns him into a convenient
• 2:55
  Speaker 1: Mexican equivalent of a European dark lord, trickster, or satanic adversary.
• 3:01
  Speaker 1: None of those comparisons can contain him without flattening the
• 3:04
  Speaker 1: very contradictions that make his role historically interesting. The Florentine
• 3:09
  Speaker 1: Codex introduces Tezcatlipoca in language that makes his scale immediately apparent.
• 3:15
  Speaker 1: The Nahuatl text describes him as a deity whose dwelling
• 3:19
  Speaker 1: or presence was understood as extending through the land of
• 3:22
  Speaker 1: the dead, the earthly world and the heavens, and portrays
• 3:25
  Speaker 1: him as capable of bringing misfortune and anxiety, and conflict,
• 3:30
  Speaker 1: while also suddenly granting prosperity and wealth. He could raise
• 3:34
  Speaker 1: somebody and destroy somebody, favor one person and overturn another,
• 3:38
  Speaker 1: which helps explain why Tezcatlipoca is repeatedly associated not simply
• 3:43
  Speaker 1: with evil, but with the terrifying instability of fortune itself.
• 3:48
  Speaker 1: That instability is crucial, because a deity who represents only
• 3:52
  Speaker 1: darkness is conceptually easy. Darkness stands opposite light, evil stands
• 3:57
  Speaker 1: opposite good, destruction stands opposite creation and the theology becomes
• 4:01
  Speaker 1: another dualistic diagram. Tezcatlipoca resists that simplicity because his power
• 4:07
  Speaker 1: appears in the fact that human circumstances can reverse without warning.
• 4:12
  Speaker 1: Wealth can disappear, authority can collapse, an enemy can rise,
• 4:16
  Speaker 1: a ruler can become vulnerable, and the person who believes
• 4:19
  Speaker 1: himself secure can discover that his security was temporary. In
• 4:24
  Speaker 1: that sense, Tezcatlipoca belongs naturally beside the system we uncovered
• 4:28
  Speaker 1: in part one. Because a world structured through unstable relationships
• 4:32
  Speaker 1: requires specialists and rituals capable of interpreting uncertainty. His very
• 4:37
  Speaker 1: name brings our problem into visual form. Tezcatlipoca is conventionally
• 4:41
  Speaker 1: translated as smoking mirror. Joining Tezcatl, mirror, with the idea
• 4:46
  Speaker 1: of smoke. Think about that combination for a moment. Because
• 4:50
  Speaker 1: a mirror is supposed to clarify while smoke obscures. And
• 4:53
  Speaker 1: a mirror reveals an image while smoke conceals one. The
• 4:56
  Speaker 1: object seems to produce certainty because it shows what stands
• 4:59
  Speaker 1: before it. Yet anyone who has spent time staring into
• 5:03
  Speaker 1: reflective darkness knows that mirrors can become strange very quickly
• 5:07
  Speaker 1: when the quality of light deteriorates. The image remains present,
• 5:12
  Speaker 1: but its edges soften, features lose stability, and the visual
• 5:15
  Speaker 1: system begins supplying information where sensory input has become ambiguous.
• 5:21
  Speaker 1: The name smoking mirror therefore contains a tension between seeing
• 5:24
  Speaker 1: and not seeing. revealing and concealing, reflection and obscurity. That
• 5:29
  Speaker 1: fits Tezcatlapoca almost too perfectly. Polished obsidian mirrors were real
• 5:34
  Speaker 1: objects in ancient Mexico, and the association between Tezcatlapoca and
• 5:39
  Speaker 1: such mirrors is not a modern occult invention. Getty's research
• 5:43
  Speaker 1: on ancient Mexican mirrors notes that polished obsidian mirrors, or tezcatl,
• 5:48
  Speaker 1: had divinatory uses and that Tezcatlapoca was repeatedly represented with
• 5:52
  Speaker 1: mirrors on the body, including the chest, headdress and, in
• 5:56
  Speaker 1: some iconographic traditions, replacing a foot. The important point is
• 6:01
  Speaker 1: not merely that he owned a magical mirror in the
• 6:03
  Speaker 1: way a fairy tale character might possess one, because the
• 6:06
  Speaker 1: mirror participates in his identity so thoroughly that reflection itself
• 6:11
  Speaker 1: becomes part of divine anatomy. And obsidian itself deserves attention
• 6:15
  Speaker 1: because this was not simply the easiest shiny substance available.
• 6:19
  Speaker 1: Obsidian is volcanic glass, created when silica-rich lava cools so
• 6:24
  Speaker 1: quickly that that crystals do not have time to form.
• 6:27
  Speaker 1: It fractures into edges so sharp that obsidian blades have
• 6:30
  Speaker 1: been used for cutting technologies across the world. But when
• 6:34
  Speaker 1: properly worked and polished, the same material becomes a reflective
• 6:37
  Speaker 1: black surface. Linking cutting with seeing and blood with reflection
• 6:42
  Speaker 1: in ways that are physically real even before we decide what,
• 6:45
  Speaker 1: if anything, ancient users made of those associations symbolically. Those
• 6:50
  Speaker 1: associations do not mean the Nawa necessarily constructed the exact
• 6:54
  Speaker 1: philosophical symbolism we might create from them today, and we
• 6:58
  Speaker 1: should not pretend that every physical property of obsidian was
• 7:01
  Speaker 1: automatically encoded into theology. What matters is that the obsidian
• 7:06
  Speaker 1: undeniably occupied multiple technological and ritual roles, and polished obsidian
• 7:11
  Speaker 1: mirrors entered contexts of elite power and supernatural vision. The
• 7:15
  Speaker 1: black surface was therefore not merely decorative, because in ritual
• 7:19
  Speaker 1: context it could become an instrument through which seeing itself
• 7:22
  Speaker 1: was recognized and interpreted. The word scrying is useful here
• 7:27
  Speaker 1: as long as we understand that it is our comparative
• 7:29
  Speaker 1: English category rather than an indigenous Nahuatl label. In European
• 7:34
  Speaker 1: occult traditions, scrying refers broadly to gazing into a reflective
• 7:38
  Speaker 1: or visually ambiguous medium, crystal, water, polished metal, dark glass,
• 7:44
  Speaker 1: or similar surfaces, with the intention of receiving images or
• 7:47
  Speaker 1: information unavailable through ordinary sight. Ancient Mexican obsidian mirrors appear
• 7:53
  Speaker 1: to have participated in divinatory practices sufficiently similar that historians
• 7:58
  Speaker 1: regularly use the comparison, although the surrounding cosmology was obviously different.
• 8:03
  Speaker 1: Getty describes these mirrors specifically as instruments associated with divination
• 8:08
  Speaker 1: and supernatural vision. What makes this especially interesting for our
• 8:12
  Speaker 1: larger project is that we can now ask two questions
• 8:15
  Speaker 1: at the same time without confusing them. The historical question
• 8:19
  Speaker 1: concerns what the mirror meant inside Nawa ritual culture, while
• 8:22
  Speaker 1: the neurological question concerns what prolonged viewing of an ambiguous
• 8:26
  Speaker 1: reflective surface can actually do to human perception. And although
• 8:31
  Speaker 1: those are not the same question, they can illuminate one
• 8:34
  Speaker 1: another if we keep their explanatory levels separate. Modern experimental
• 8:38
  Speaker 1: psychology provides a particularly strange example of how visual ambiguity
• 8:43
  Speaker 1: can interact with face processing under controlled conditions. In 2010,
• 8:49
  Speaker 1: psychologist Giovanni Caputo published a short study describing what he
• 8:53
  Speaker 1: called the strange face in the mirror illusion, in which
• 8:56
  Speaker 1: participants gazing at their own reflected faces under low illumination
• 9:01
  Speaker 1: reported substantial distortions, unfamiliar faces, animal-like forms, and fantastic or
• 9:07
  Speaker 1: monstrous appearances emerging during prolonged viewing. Caputo proposed that instability
• 9:13
  Speaker 1: in facial processing under reduced visual information could contribute to
• 9:17
  Speaker 1: the experience, and later work has continued to reproduce strange
• 9:21
  Speaker 1: face phenomena under mirror gazing and interpersonal gazing conditions. A
• 9:28
  Speaker 1: 2023 systematic review is useful here because it both strengthens
• 9:31
  Speaker 1: and limits the claim.
• 9:33
  Speaker 2: Strange face illusions.
• 9:34
  Speaker 1: Appear to be reproducible perceptual phenomena, particularly under reduced light,
• 9:40
  Speaker 1: prolonged fixation, and face-focused viewing. but reported prevalence varies substantially
• 9:46
  Speaker 1: with study quality and experimental design, which means we should
• 9:50
  Speaker 1: not treat the original dramatic percentages from small mirror studies
• 9:54
  Speaker 1: as a universal law of human perception. None of this
• 9:57
  Speaker 1: proves that Nahuatl diviners were hallucinating Tezcatlipoca because they stared
• 10:01
  Speaker 1: into mirrors, and it would be irresponsible to say otherwise,
• 10:05
  Speaker 1: because we do not know that ancient Mexican mirror use
• 10:08
  Speaker 1: reproduced those laboratory conditions or precisely what techniques individual practitioners employed.
• 10:14
  Speaker 1: What the research demonstrates is something more modest and more useful.
• 10:18
  Speaker 1: namely that human visual perception can become unstable when faces
• 10:22
  Speaker 1: and reflections are viewed under conditions of weak sensory information
• 10:26
  Speaker 1: and prolonged fixation. Vision is not a camera producing a
• 10:30
  Speaker 1: perfect internal photograph. The brain is constantly integrating incomplete sensory
• 10:35
  Speaker 1: information with expectation, memory, pattern recognition, and prediction. When incoming
• 10:42
  Speaker 1: information becomes weak or ambiguous, those internal processes matter more,
• 10:47
  Speaker 1: Faces are especially powerful stimuli because the human nervous system
• 10:51
  Speaker 1: is extraordinarily sensitive to facial structure. And when that structure
• 10:56
  Speaker 1: begins fading or distorting under low illumination and prolonged fixation,
• 11:00
  Speaker 1: perception can produce remarkably strange results. Now imagine that process
• 11:05
  Speaker 1: occurring not in a psychology laboratory, but inside a culture
• 11:09
  Speaker 1: where the mirror already possesses ritual significance, where a trained
• 11:13
  Speaker 1: specialist approaches the object expecting hidden information. where the surface
• 11:17
  Speaker 1: itself belongs iconographically to a god associated with fate, night,
• 11:21
  Speaker 1: and supernatural vision, and where the experience is interpreted through
• 11:25
  Speaker 1: stories and categories learned from childhood. The neurological mechanism does
• 11:29
  Speaker 1: not destroy the ritual experience, because it explains one layer
• 11:33
  Speaker 1: of how the experience can become possible while culture supplies
• 11:37
  Speaker 1: the interpretive framework through which the resulting experience acquires meaning.
• 11:41
  Speaker 1: That distinction is one of the major arguments running throughout
• 11:44
  Speaker 1: this project. A neuroscience could observe changes in visual processing
• 11:49
  Speaker 1: and explain why ambiguous forms emerge. A Nahual ritual specialist
• 11:53
  Speaker 1: could interpret those forms as information concerning divine or hidden realities.
• 11:58
  Speaker 1: Those interpretations belong to different explanatory systems and neither can
• 12:02
  Speaker 1: simply be substituted for the other. What makes the mirror
• 12:05
  Speaker 1: so powerful is that it sits exactly at the boundary
• 12:08
  Speaker 1: between them. The physical object reflects light. The visual system
• 12:13
  Speaker 1: interprets the reflection. and the ritual system interprets that interpretation.
• 12:18
  Speaker 1: Then history adds another layer entirely, because one of these
• 12:21
  Speaker 1: Mexican obsidian mirrors eventually crossed the Atlantic. John Dee is
• 12:26
  Speaker 1: one of the unavoidable figures in the history of Western
• 12:28
  Speaker 1: ceremonial magic. Mathematician, astrologer, scholar, navigator, advisor to Elizabeth I,
• 12:36
  Speaker 1: collector of manuscripts, and practitioner of a form of angelic
• 12:39
  Speaker 1: communication that would later become enormously influential within Western occultism.
• 12:45
  Speaker 1: Dee and his better-known scrying associate, Edward Kelly, conducted complex
• 12:49
  Speaker 1: sessions in which spiritual beings were reportedly contacted through reflective objects,
• 12:54
  Speaker 1: including crystals and stones. Among the objects later associated with
• 12:59
  Speaker 1: Dee was a circular polished black mirror made of obsidian.
• 13:03
  Speaker 1: For centuries, people speculated that the mirror might have come
• 13:06
  Speaker 1: from Mexico. In 2021, a team led by archaeologist Stuart
• 13:10
  Speaker 1: Campbell and colleagues published a geochemical study in the journal
• 13:14
  Speaker 1: Antiquity that essentially settled the geological question. Using non-destructive compositional analysis,
• 13:21
  Speaker 1: the research compared the obsidian used in several British museum
• 13:25
  Speaker 1: mirrors with known geological sources and concluded that these mirror
• 13:29
  Speaker 1: was made from Mexican obsidian, specifically material associated with the
• 13:33
  Speaker 1: Pachuca source. Other obsidian objects in the collection were also
• 13:37
  Speaker 1: proved Mexican, although some came from different geological sources. That
• 13:42
  Speaker 1: is one of the most extraordinary material connections in the
• 13:44
  Speaker 1: entire history of Western occultism. An object manufactured from Mexican
• 13:49
  Speaker 1: volcanic glass in a cultural environment where obsidian mirrors possessed
• 13:53
  Speaker 1: ritual and divinatory significance crossed into Europe after the Spanish
• 13:57
  Speaker 1: conquest and eventually became associated with an English ceremonial magician
• 14:02
  Speaker 1: whose practices also involved reflective vision. but this is exactly
• 14:06
  Speaker 1: where we have to resist the temptation to create a
• 14:09
  Speaker 1: more dramatic story than the evidence supports. There is no
• 14:12
  Speaker 1: good evidence that John Dee was initiated into a secret
• 14:15
  Speaker 1: Tezcatlipoca cult. There is no evidence that a surviving Mexico
• 14:19
  Speaker 1: priest handed Dee instructions for operating the mirror. Some say
• 14:24
  Speaker 1: there is no evidence that he even used it. There
• 14:27
  Speaker 1: is no evidence that Dee understood the full indigenous cosmological
• 14:30
  Speaker 1: meaning of the object. The antiquity study itself is careful
• 14:34
  Speaker 1: about the distinctions. because its importance lies in demonstrating the
• 14:38
  Speaker 1: Mexican origin of the mirror and examining how an indigenous
• 14:41
  Speaker 1: object accumulated new meanings as it entered a radically different
• 14:45
  Speaker 1: cultural system. That is exactly more interesting than claiming a
• 14:49
  Speaker 1: hidden line of transmission, because the mirror experienced a second life.
• 14:54
  Speaker 1: In central Mexico, polished obsidian mirrors existed inside systems involving
• 14:58
  Speaker 1: divine power, elite identity, and divination, while in 16th century Europe,
• 15:04
  Speaker 1: An imported black mirror could become absorbed into traditions of
• 15:07
  Speaker 1: crystal gazing, angelic communication, and natural magic, meaning that the
• 15:12
  Speaker 1: same stone moved between cosmologies while remaining materially Mexican even
• 15:17
  Speaker 1: as its cultural meaning changed. That is a perfect example
• 15:21
  Speaker 1: of why material culture matters. Ideas do not have to
• 15:24
  Speaker 1: travel intact for objects to create connections between intellectual worlds.
• 15:29
  Speaker 1: An object can be removed from one system and interpreted
• 15:32
  Speaker 1: inside another while still carrying physical traces of its origin.
• 15:37
  Speaker 1: So when somebody says that John Dee possessed an Aztec
• 15:39
  Speaker 1: obsidian mirror, we can finally say something very precise. Geochemical
• 15:44
  Speaker 1: analysis strongly supports a Mexican origin. Obsidian mirrors had ritual
• 15:48
  Speaker 1: and divinatory associations in ancient Mexico, and the object later
• 15:53
  Speaker 1: became associated with one of Europe's most famous occultists. But
• 15:57
  Speaker 1: none of that proves that Dee was performing Nahua ritual.
• 16:00
  Speaker 1: What the evidence securely gives us is a Mexican obsidian
• 16:03
  Speaker 1: mirror from a cultural tradition in which such objects could
• 16:07
  Speaker 1: possess ritual and divinatory significance, crossing the Atlantic and entering
• 16:12
  Speaker 1: the biography of European ceremonial magic. So the mirror changed worlds,
• 16:17
  Speaker 1: even though the basic human visual and nervous system confronting
• 16:20
  Speaker 1: a dark reflective surface remained the same. And that brings
• 16:24
  Speaker 1: us toward the next layer of this investigation. because the
• 16:28
  Speaker 1: mirror was only one way to modify ordinary perception, while
• 16:31
  Speaker 1: plants could alter the same perceptual system chemically rather than
• 16:35
  Speaker 1: through ambiguous reflection. The 11th book of the Florentine Codex
• 16:40
  Speaker 1: is often described as dealing with the natural world, but
• 16:43
  Speaker 1: anyone expecting something resembling a modern botanical textbook will quickly
• 16:47
  Speaker 1: discover that medicinal, sensory, and ritual categories constantly overlap. Plants
• 16:53
  Speaker 1: are described according to appearance, habitat, taste, smell, and practical uses,
• 16:58
  Speaker 1: but some are also described as substances capable of profoundly
• 17:02
  Speaker 1: changing consciousness. One of the clearest examples is ololiloquy, whose
• 17:07
  Speaker 1: historical descriptions in modern chemistry can be placed beside one
• 17:11
  Speaker 1: another without pretending that chemistry exhausts the plant's ritual meaning.
• 17:15
  Speaker 1: The Florentine Codex describes a plant called Coltozoxoquy, and its
• 17:20
  Speaker 1: seed ololiquy, stating that ingestion could derange or intoxicate the
• 17:24
  Speaker 1: person and cause terrifying visions. The same passage also gives
• 17:28
  Speaker 1: medicinal uses, demonstrating immediately why our modern separation between drug, medicine,
• 17:34
  Speaker 1: and ritual plant can become misleading when applied retrospectively. Modern
• 17:39
  Speaker 1: phytochemistry helps explain why those reports cannot simply be dismissed
• 17:43
  Speaker 1: as superstition. Seeds historically identified with alliloquy, especially Turbina corumbosa,
• 17:50
  Speaker 1: formerly classified as Rivia corumbosa, contain ergoline alkaloids including lysergic
• 17:55
  Speaker 1: acid amide, usually called ergine or LSA, along with related compounds.
• 18:01
  Speaker 1: But modern botany adds an important complication that makes the
• 18:04
  Speaker 1: chemistry even stranger. Much of that ergoline production is associated
• 18:08
  Speaker 1: with symbiotic fungi of the genus Periglandula that live with
• 18:13
  Speaker 1: the morning glory host and synthesize alkaloids that are then
• 18:17
  Speaker 1: found in the plant's tissues and seeds. The psychoactive chemistry
• 18:21
  Speaker 1: is therefore not simply a property of an isolated plant
• 18:24
  Speaker 1: molecule factory, but part of a plant-fungus biological partnership, while
• 18:29
  Speaker 1: the compounds themselves belong to the broader lysergamide family that
• 18:32
  Speaker 1: includes LSD, even though their potency, pharmacokinetics, and subjective effects
• 18:38
  Speaker 1: differ substantially. Again, the scientific explanation does not tell us
• 18:42
  Speaker 1: what an oliloquy vision meant to a NAWA participant. It
• 18:46
  Speaker 1: tells us something crucially different. which is that the botanical complex,
• 18:50
  Speaker 1: hysterically identified with alloliloquy, contains compounds capable of altering consciousness.
• 18:57
  Speaker 1: So the reports of profound perceptual change cannot be dismissed
• 19:00
  Speaker 1: merely because the plant also occupied a sacred or ritual context.
• 19:06
  Speaker 1: A much clearer case is peyote, or peyote, whose chemistry
• 19:10
  Speaker 1: gives us a different route into altered perception. The Florentine
• 19:14
  Speaker 1: Codex describes peyote as growing toward the northern region and
• 19:17
  Speaker 1: states that people who consumed it could experience visions characterized
• 19:21
  Speaker 1: as frightening or amusing. Elsewhere, the manuscript also treats peyote medicinally,
• 19:27
  Speaker 1: again refusing our modern demand that a substance belong either
• 19:30
  Speaker 1: in a pharmacy or in a religious ceremony, but not both. Today,
• 19:35
  Speaker 1: we know that peyote contains numerous alkaloids, the most famous
• 19:39
  Speaker 1: being mescaline, a phenethylamine psychedelic whose effects are mediated substantially
• 19:44
  Speaker 1: through serotonergic signaling. and specialty activity at 5HT2A. and 5-HT2C receptors,
• 19:52
  Speaker 1: with the hallucinogenic effects of classical psychedelics most strongly associated
• 19:57
  Speaker 1: with 5-HT2A agonism. Modern reviews describe changes in perception, emotional experience, thought,
• 20:05
  Speaker 1: and sense of self that can persist for many hours.
• 20:09
  Speaker 1: making peyote a particularly clear example of a plant whose
• 20:13
  Speaker 1: historically reported visionary effects are compatible with well-characterized psychoactive pharmacology.
• 20:19
  Speaker 1: That gives us a rare situation in historical research where
• 20:23
  Speaker 1: a chronicler says essentially this plant causes visions and modern
• 20:27
  Speaker 1: pharmacology can confirm that the plant contains a compound capable
• 20:31
  Speaker 1: of doing exactly that. The mushroom material requires slightly more
• 20:36
  Speaker 1: taxonomic caution because the colonial terminology does not map cleanly
• 20:40
  Speaker 1: onto one modern species' name. Nahuatl sources use terms including
• 20:45
  Speaker 1: nonoctil and teononoctil, with the latter often translated in popular
• 20:49
  Speaker 1: literature as divine mushroom or god's flesh, although the exact
• 20:54
  Speaker 1: cultural implications of the compound word deserves more care than
• 20:58
  Speaker 1: that memorable English gloss usually receives. The Floritine Codex describes
• 21:03
  Speaker 1: mushroom consumption producing visions that could be frightening or amusing.
• 21:07
  Speaker 1: which establishes the altered state claim much more securely than
• 21:10
  Speaker 1: any attempt to force a 16th century name onto one
• 21:13
  Speaker 1: modern species. Later ethnomycological work in Mexico connects indigenous visionary
• 21:19
  Speaker 1: mushroom traditions with psilocybin-containing species, but the colonial text itself
• 21:25
  Speaker 1: should not be treated as though Sahagin supplied a modern
• 21:28
  Speaker 1: taxonomic identification. Where psilocybin is present, the body converts it
• 21:33
  Speaker 1: to psilocin, And modern psychedelic neuroscience has shown that serotonergic
• 21:38
  Speaker 1: psychedelics can profoundly alter visual processing, network connectivity, self-referential processing,
• 21:44
  Speaker 1: and the relationship between sensory input and internally generated imagery.
• 21:49
  Speaker 1: A study published online in 2024 and in Molecular Psychiatry
• 21:53
  Speaker 1: in 2025 examined how psilocybin changes affective connectivity within visual
• 21:59
  Speaker 1: networks in ways that can increase the contribution of top-down
• 22:02
  Speaker 1: processes to complex internally generated imagery rather than merely producing
• 22:08
  Speaker 1: simple distortions of incoming light. Again, we should slow down
• 22:12
  Speaker 1: before turning this into the simplistic claim that because psilocybin
• 22:16
  Speaker 1: acts through serotonergic systems, the gods encountered in those experiences
• 22:20
  Speaker 1: were somehow reducible to serotonin. What the neurochemistry tells us
• 22:25
  Speaker 1: is how the human nervous system can enter states in
• 22:28
  Speaker 1: which internally generated imagery, memory, emotion, sensory processing, and self-representation
• 22:34
  Speaker 1: interact in unusual ways, while now our culture tells us
• 22:38
  Speaker 1: how such states could be interpreted, socially contained, and given meaning.
• 22:43
  Speaker 1: It is the same distinction we saw with the mirror,
• 22:45
  Speaker 1: because mechanism creates the conditions of possibility while culture supplies interpretation.
• 22:51
  Speaker 1: And then we reach a completely different class of plant,
• 22:54
  Speaker 1: the Taur, which demonstrates why the generic modern category hallucinogen
• 22:59
  Speaker 1: can be dangerously misleading. because the Florentine Codex refers to
• 23:03
  Speaker 1: plants identified in later botanical scholarship with the Tora species,
• 23:07
  Speaker 1: including Toloa and Tlopatl, describing medicinal applications and emphasizing cautious
• 23:13
  Speaker 1: or limited use in some contexts. The Tora does not
• 23:17
  Speaker 1: work like peyote or psilocybin, because its principal psychoactive compounds
• 23:22
  Speaker 1: include tropane alkaloids such as atropine, hyosiamine, and scopolamine, which
• 23:28
  Speaker 1: disrupt muscarinic acetylcholine signaling. rather than primarily acting through the
• 23:33
  Speaker 1: serotonergic mechanisms characteristic of classical psychedelics. At sufficiently toxic exposure,
• 23:40
  Speaker 1: antimuscarinic effects can produce profound delirium, confusion, memory impairment, and
• 23:46
  Speaker 1: realistic hallucinations, alongside potentially dangerous cardiovascular, neurological, and autonomic effects.
• 23:54
  Speaker 1: Modern toxicology treats anticholinergic delirium as a medical emergency rather
• 23:59
  Speaker 1: than as a conventional psychedelic state. That difference is crucial,
• 24:03
  Speaker 1: because although a person using a classic psychedelic may retain
• 24:07
  Speaker 1: some awareness that perception has been altered, severe anticholinergic delirium
• 24:12
  Speaker 1: can destroy that distinction so thoroughly that hallucinated people or
• 24:16
  Speaker 1: objects may be treated as completely real while the body
• 24:20
  Speaker 1: is simultaneously experiencing potentially dangerous physiological toxicity. Whenever historical sources
• 24:26
  Speaker 1: mention detour-like plants in ritual or medicinal environments, We therefore
• 24:31
  Speaker 1: have to resist romanticizing them as simply another visionary herb,
• 24:35
  Speaker 1: because these plants can be extremely dangerous. The fact that
• 24:39
  Speaker 1: ancient people use them does not make unsupervised experimentation sensible.
• 24:44
  Speaker 1: There is no reason to reproduce ancient preparations to understand
• 24:47
  Speaker 1: their history. The pharmacology already tells us something important. The
• 24:51
  Speaker 1: Nawa Materia Medica included plants capable of altering consciousness through
• 24:56
  Speaker 1: dramatically different neurochemical pathways. One more plant deserves attention because
• 25:01
  Speaker 1: it illustrates the opposite danger, the temptation to label every
• 25:05
  Speaker 1: aromatic ritual plant as psychedelic. The Florentine Codex describes Yautli,
• 25:11
  Speaker 1: generally identified with Targetus lucida, Mexican tarragon, or Mexican marigold,
• 25:16
  Speaker 1: as an aromatic medicinal plant. The text describes its smell
• 25:20
  Speaker 1: and medicinal applications rather than presenting it simply as a hallucinogen.
• 25:25
  Speaker 1: Modern experimental work on Tagetus lucida has found anxiolytic and
• 25:30
  Speaker 1: sedative-like effects in animal models and has investigated serotonergic and
• 25:35
  Speaker 1: gabaergic mechanisms, but that is not equivalent to proving that
• 25:38
  Speaker 1: the plant produced visionary states during ancient rituals.
• 25:42
  Speaker 2: That distinction matters because.
• 25:44
  Speaker 1: Older occult literature has a tendency to take any plant
• 25:47
  Speaker 1: found in a ceremony and promote it immediately to an entheogen.
• 25:51
  Speaker 1: Sometimes incense is functioning primarily as incense, Medicine is functioning
• 25:56
  Speaker 1: primarily as medicine. An aromatic plant may affect mood without
• 26:00
  Speaker 1: producing hallucinations. And a genuinely powerful pharmacological plant may transform perception.
• 26:07
  Speaker 1: The interesting question is therefore not how many substances we
• 26:10
  Speaker 1: can force into the label psychedelic. It is how many
• 26:13
  Speaker 1: multiple sensory and physiological technologies could be combined inside ritual environments.
• 26:18
  Speaker 1: Because a plant rarely operates in isolation from everything surrounding it.
• 26:24
  Speaker 1: There are three substances we need to put into this
• 26:26
  Speaker 1: picture before moving from individual plants into the larger ritual environment.
• 26:31
  Speaker 1: Because focusing only on famous visionary materials such as peyote, oliloquy, mushrooms,
• 26:36
  Speaker 1: and datura can accidentally make Nawa altered state practice look
• 26:41
  Speaker 1: more exotic and more pharmacologically specialized than the surviving sources
• 26:45
  Speaker 1: actually suggest. Tobacco, fermented agave drink, and aromatic resin may
• 26:51
  Speaker 1: sound less dramatic to a modern audience, precisely because versions
• 26:55
  Speaker 1: of all three remain familiar, but familiarity can hide how
• 26:58
  Speaker 1: powerfully they act on attention, arousal, social behavior, and the
• 27:03
  Speaker 1: sensory atmosphere of ritual. The first is Paisietal, the tobacco
• 27:07
  Speaker 1: described in Book 11 of the Florentine Codex, where the
• 27:11
  Speaker 1: text says that the leaves could be ground with lime
• 27:14
  Speaker 1: and placed in the lips or chewed, while also describing
• 27:18
  Speaker 1: effects that include intoxication, dizziness, possession-like alteration, and suppression of hunger.
• 27:24
  Speaker 1: Historical botanical identifications have associated Paisieto especially with Nicotiana rustica,
• 27:31
  Speaker 1: although older scholarship also raised Nicotiana tobacco in the identification history.
• 27:37
  Speaker 1: So the safest language is not to pretend that every
• 27:39
  Speaker 1: occurrence of the Nawa'u term gives us a laboratory-confirmed species specimen.
• 27:45
  Speaker 1: What matters for the neurological argument is that tobacco is
• 27:48
  Speaker 1: not merely fragrant smoke. because nicotine is a potent drug
• 27:51
  Speaker 1: acting at nicotinic acetylcholine receptors, where it changes neurotransmitter release
• 27:57
  Speaker 1: and can alter attention, arousal, autonomic activity, appetite, and reward.
• 28:03
  Speaker 1: Nicotiana rustica is also generally capable of containing substantially more
• 28:08
  Speaker 1: nicotine than the milder commercial tobacco familiar to many modern smokers,
• 28:13
  Speaker 1: which helps explain why indigenous tobacco preparations should not automatically
• 28:18
  Speaker 1: be imagined as equivalent to casually smoking a modern cigarette.
• 28:23
  Speaker 1: The same book 11 material makes the technological range even
• 28:26
  Speaker 1: clearer by describing another tobacco-like preparation. It's Seattle, being placed
• 28:32
  Speaker 1: in a smoking tube together with pine resin, which means
• 28:35
  Speaker 1: that the Nawa sensory environment could combine plant alkaloids with
• 28:40
  Speaker 1: resinous smoke through an intentional delivery device rather than through
• 28:44
  Speaker 1: some vague category called incense. That distinction matters because the
• 28:48
  Speaker 1: route of administration changes pharmacology, while smoke simultaneously changes the
• 28:53
  Speaker 1: ritual room itself through odor, visibility, and respiratory sensation. So
• 28:59
  Speaker 1: a smoked or orally absorbed substance can operate at once
• 29:02
  Speaker 1: as chemistry inside the participant and as atmosphere surrounding the participant.
• 29:08
  Speaker 1: Then there is polk or akli, the fermented drink made
• 29:12
  Speaker 1: from agave sap. which is one of the most important
• 29:14
  Speaker 1: altered state substances that disappears when modern discussions of indigenous
• 29:18
  Speaker 1: religion become obsessed exclusively with psychedelics. The Florentine Codex repeatedly
• 29:24
  Speaker 1: places Polk inside regulated ceremonial contexts, including festival drinking by
• 29:29
  Speaker 1: elders and other authorized participants, special ritual preparations, libations, and
• 29:35
  Speaker 1: rites connected with deities of intoxication, while other passages make
• 29:39
  Speaker 1: equal clear that drinking could be socially restricted and punished
• 29:43
  Speaker 1: when it occurred outside permitted circumstances. That combination is crucial
• 29:49
  Speaker 1: because alcohol was not simply a recreational substance floating freely
• 29:54
  Speaker 1: through the culture. Intoxication could be ritualized, scheduled, socially allocated,
• 29:59
  Speaker 1: and and interpreted through a religious vocabulary that included divine
• 30:03
  Speaker 1: beings associated with pulp and drunkenness. The neurochemistry here is
• 30:08
  Speaker 1: less exotic than mescaline or psilocybin, only because ethanol is
• 30:11
  Speaker 1: familiar to us. Acute ethanol exposure affects multiple neural systems,
• 30:17
  Speaker 1: and increasing intoxication can alter judgment, motor coordination, emotional regulation, memory,
• 30:23
  Speaker 1: social inhibition, and eventually consciousness itself. which means that a
• 30:28
  Speaker 1: ceremony involving controlled drinking already contains a powerful consciousness-altering technology
• 30:34
  Speaker 1: without requiring any rare hallucinogenic plan. The Florentine Codex even
• 30:39
  Speaker 1: preserves scenes in which participants become visibly intoxicated, quarrel, cry, boast, dance,
• 30:46
  Speaker 1: fall asleep, or require social reconciliation afterward, giving us a
• 30:51
  Speaker 1: rare case where the historical text records not only the
• 30:54
  Speaker 1: ritual permission to drink, but recognizable behavioral consequences of intoxication.
• 31:01
  Speaker 1: That observation also protects us from another mistake, because altered
• 31:04
  Speaker 1: states are not synonymous with visionary states. A substance does
• 31:08
  Speaker 1: not need to produce geometric imagery, gods, or hallucinations in
• 31:13
  Speaker 1: order to alter the ritual mind. An alcohol can reduce inhibition,
• 31:17
  Speaker 1: intensify group emotion, disrupt memory, impair judgment, and change the
• 31:22
  Speaker 1: way participants experience music, movement, fear, or social permission. If
• 31:27
  Speaker 1: our subject is the deliberate alteration of consciousness, rather than
• 31:31
  Speaker 1: a modern catalog of psychedelics, Polk belongs in the center
• 31:34
  Speaker 1: of the discussion. Finally, there is Copal, a resin that
• 31:39
  Speaker 1: appears repeatedly in the Florentine Codex, not merely as a
• 31:43
  Speaker 1: botanical material, but as an offering burned in incense burners
• 31:47
  Speaker 1: and carried into temple context. With Book 2 describing white
• 31:51
  Speaker 1: copal among ritual offerings and other passages placing copal directly
• 31:55
  Speaker 1: in the equipment of religious specialists. The important correction here
• 31:59
  Speaker 1: is that we do not need to pretend copal was
• 32:02
  Speaker 1: a psychedelic in order for it to matter neurologically. Because
• 32:06
  Speaker 1: burning aromatic resin changes the olfactory landscape of a room,
• 32:10
  Speaker 1: produces visible smoke, marks a transition from ordinary space into
• 32:15
  Speaker 1: ritual space, and creates a sensory cue capable of becoming
• 32:18
  Speaker 1: strongly associated with expectation, memory, and sacred action through repetition.
• 32:25
  Speaker 1: That is exactly the kind of mechanism that gets lost
• 32:27
  Speaker 1: when every ritual plant is evaluated according to the single
• 32:31
  Speaker 1: question of whether it contains a famous hallucinogen. Paisielo reminds
• 32:37
  Speaker 1: us that cholinergic pharmacology and stimulant intoxicant effects mattered. Polk
• 32:42
  Speaker 1: reminds us that ethanol and socially regulated intoxication mattered. Culper
• 32:47
  Speaker 1: reminds us that a substance can transform perception through smell, smoke,
• 32:51
  Speaker 1: learned association, and atmosphere without producing a classic drug-induced hallucination
• 32:56
  Speaker 1: at all. Once those three are restored to the picture,
• 33:00
  Speaker 1: alongside peyote, alliloquy, mushrooms, and detourer, the Nahual ritual environment
• 33:05
  Speaker 1: stops looking like a collection of isolated magical ingredients and
• 33:09
  Speaker 1: starts looking much more like what the sources actually preserve,
• 33:13
  Speaker 1: a layered sensory system in which chemistry, social permission, expectation, odor, smoke,
• 33:20
  Speaker 1: bodily state, and religious interpretation could converge. Imagine approaching the
• 33:25
  Speaker 1: ritual not as a list of symbolic actions, but as
• 33:28
  Speaker 1: an environment constructed around a nervous system. Because once you
• 33:32
  Speaker 1: alter when a person sleeps, what they eat, how much
• 33:35
  Speaker 1: light reaches them, which sounds surround them, which movements and
• 33:39
  Speaker 1: words are repeated, which intense odors fill the space, what
• 33:43
  Speaker 1: they expect and fear, how much pain or social pressure
• 33:46
  Speaker 1: they experience, which sacred images are placed before them, what
• 33:50
  Speaker 1: kind of presence they have been taught to anticipate, and,
• 33:53
  Speaker 1: in some circumstances, which psychoactive chemistry enters the body. You
• 33:58
  Speaker 1: are no longer manipulating one isolated variable, but an entire
• 34:02
  Speaker 1: perceptual ecology. Nothing about that requires ancient people to understand neurons.
• 34:08
  Speaker 1: Ritual traditions throughout the world discovered through repeated cultural experimentation
• 34:13
  Speaker 1: that manipulating the body changes experience. Modern neuroscience simply gives
• 34:19
  Speaker 1: us another vocabulary for explaining why. Sleep deprivation provides one
• 34:24
  Speaker 1: obvious example, because extended wakefulness can produce perceptual distortions, emotional instability, depersonalization,
• 34:32
  Speaker 1: and eventually hallucinations. A systematic review examining historical sleep deprivation
• 34:38
  Speaker 1: experiments found perceptual changes appearing reliably as wakefulness became prolonged.
• 34:44
  Speaker 1: Visual disturbances especially common and more complex hallucinatory phenomena emerging
• 34:50
  Speaker 1: as sleep loss became severe. That does not mean every
• 34:53
  Speaker 1: Nawa night vigil involved enough sleep loss to produce hallucinations.
• 34:57
  Speaker 1: It meant that prolonged waking is a genuine consciousness-altering technique,
• 35:01
  Speaker 1: whether its practitioners understand the underlying biology or not. Fasting
• 35:07
  Speaker 1: can likewise modify attention, weakness, arousal, and bodily sensation, particularly
• 35:13
  Speaker 1: when combined with exertion and sleep disruptions. Rhythmic movement and
• 35:18
  Speaker 1: repetitive vocalization alter respiration, sensory attention, and social synchronization. Breathing
• 35:25
  Speaker 1: itself is tightly linked with brainstem regulatory systems and broader
• 35:29
  Speaker 1: networks involved in emotion and arousal. Modern neuroscience increasingly treats
• 35:35
  Speaker 1: respiratory rhythm as something that interacts with cognition rather than
• 35:39
  Speaker 1: merely supplying oxygen. Pain adds another layer because it is
• 35:43
  Speaker 1: not a simple signal traveling from damaged tissue into an
• 35:47
  Speaker 1: otherwise passive brain. It is an experience constructed through sensory input, expectation, attention, emotion, memory,
• 35:56
  Speaker 1: and context. Rituals that intentionally produce painful stimulation therefore do
• 36:02
  Speaker 1: more than damage tissue. They create powerful emotionally salient events
• 36:07
  Speaker 1: that can be encoded strongly into memory and social identity.
• 36:12
  Speaker 1: Cultural neuroscience has specifically examined the way intense ritual sensory
• 36:16
  Speaker 1: stimulation including pain, discomfort, loud sound, and coordinated activity can
• 36:22
  Speaker 1: reinforce learning and bind social meaning to embodied experience. Smoke, scent,
• 36:29
  Speaker 1: and darkness add another set of mechanisms because olfaction has
• 36:34
  Speaker 1: unusually direct relationships with limbic and memory system which helps
• 36:39
  Speaker 1: explain why smells can evoke emotional memories with extraordinary force.
• 36:44
  Speaker 1: Darkness reduces the precision of visual information and forces perception
• 36:48
  Speaker 1: to rely more heavily upon expectation and pattern completion. Smoke
• 36:54
  Speaker 1: physically alters the visual environment, obscuring edges and producing movement
• 36:58
  Speaker 1: whose source is difficult to localize. Place an obsidian mirror
• 37:03
  Speaker 1: into that environment and the mirror does not need supernatural
• 37:06
  Speaker 1: optics because ordinary human vision can supply the instability. place
• 37:11
  Speaker 1: Tezcatlipoca behind the mirror conceptually, and culture supplies an identity
• 37:16
  Speaker 1: through which ambiguous forms can be interpreted. So by the
• 37:19
  Speaker 1: time we ask the participant what they saw, we are
• 37:22
  Speaker 1: looking at the convergence of sensory physiology, expectation, memory, and
• 37:27
  Speaker 1: ritual meaning rather than a single isolated mechanism. Individual mechanisms
• 37:33
  Speaker 1: that appear modest in isolation can be stacked. Sleep loss, fasting, fear,
• 37:39
  Speaker 1: repetitive sound, darkness, strong scent, social expectation, pain, a reflective surface,
• 37:46
  Speaker 1: and perhaps psychoactive chemistry. So the resulting state is not
• 37:50
  Speaker 1: reducible to one mechanism because ritual operates through convergence. Modern
• 37:56
  Speaker 1: experimental science often isolates variables deliberately so researchers can determine causation,
• 38:02
  Speaker 1: whereas ritual frequently does the opposite by combining variables because
• 38:06
  Speaker 1: its practical goal is not to explain consciousness, but to
• 38:10
  Speaker 1: change experience. This may be the most important scientific insight
• 38:15
  Speaker 1: in Part 2. Because ritual is not primitive neuroscience, yet
• 38:20
  Speaker 1: many rituals can function as culturally developed technologies for controlling attention, arousal, expectation,
• 38:27
  Speaker 1: sensory input, and bodily state without anyone possessing a modern
• 38:31
  Speaker 1: theory of neurons or receptors. That is enough to produce
• 38:36
  Speaker 1: extraordinary human experiences without requiring us to either dismiss those
• 38:41
  Speaker 1: experiences as imagery or to accept every supernatural interpretation literally.
• 38:47
  Speaker 1: The body, perception, and emotion can all change under those conditions,
• 38:51
  Speaker 1: while the meaning assigned to those changes remains inseparable from
• 38:55
  Speaker 1: the cultural framework in which the experience takes place. And
• 38:59
  Speaker 1: nowhere does that become more physically obvious than when the
• 39:02
  Speaker 1: ritual body begins giving up part of itself. There is
• 39:06
  Speaker 1: one sensory system we have not given enough historical weight yet.
• 39:11
  Speaker 2: Hearing.
• 39:12
  Speaker 1: If we imagine Nawa ritual only through codex images, smoke, mirrors,
• 39:17
  Speaker 1: and plants, we accidentally turn a multi-sensory performance into a
• 39:21
  Speaker 1: silent picture. The written and pictorial sources preserve drums, rattles, bells, songs, cries,
• 39:28
  Speaker 1: and coordinated dances. as part of ceremonial life. The tepanazli,
• 39:33
  Speaker 1: a horizontal slit drum, and the we'o'we'o, an upright membrane drum,
• 39:38
  Speaker 1: appear repeatedly in description of dances and ritual settings. While
• 39:42
  Speaker 1: pre-Hispanic genres such as the tepanaz cuico, literally a log
• 39:46
  Speaker 1: drum song, make it difficult to separate verbal art from performance, rhythm,
• 39:50
  Speaker 1: and movement. That matters because sound is not simply decoration
• 39:54
  Speaker 1: surrounding the ritual. Repetition can structure attention and expectation. A
• 39:59
  Speaker 1: recurring beat makes time bodily measurable. Coordinated movement and singing
• 40:04
  Speaker 1: synchronize groups through shared timing, breathing, and motor activity. Sudden
• 40:09
  Speaker 1: changes in volume or tempo can alter arousal. High-pitched cries, rattles, drums,
• 40:15
  Speaker 1: and masked voices can make a ceremonial space feel physically
• 40:19
  Speaker 1: different long before anybody consumes a psychoactive plant or stares
• 40:23
  Speaker 1: into a mirror. None of that proves that a particular
• 40:27
  Speaker 1: Nawa song automatically produced trance. The evidence does not justify
• 40:31
  Speaker 1: a universal claim like that, and rhythm causes trance would
• 40:35
  Speaker 1: be exactly the kind of neurological shortcut we have been
• 40:38
  Speaker 1: trying to avoid. The stronger point is that the Nawa
• 40:42
  Speaker 1: ceremony possessed an acoustic architecture as well as a visual one.
• 40:48
  Speaker 1: A 2016 study by Agnieszka Brylak on pre-Hispanic Tiponez Cuicol
• 40:52
  Speaker 1: emphasizes how barely Western categories such as song, poem, and
• 40:56
  Speaker 1: theater can divide a form that originally existed through performance.
• 41:00
  Speaker 1: More recent scholarship has even approached the Florentine Codex from listening,
• 41:05
  Speaker 1: asking what traces of an originally oral, rhythmic, and melodic
• 41:09
  Speaker 1: world remain embedded inside a manuscript that modern readers normally
• 41:13
  Speaker 1: encounter with their eyes alone. Put that acoustic layer back
• 41:17
  Speaker 1: beside darkness, smoke, incense, repetitive movement, fasting, pain, expectation, and
• 41:23
  Speaker 1: psychoactive chemistry, and the ritual environment becomes more complete. The
• 41:28
  Speaker 1: participant was not merely looking at sacred things. The participant
• 41:32
  Speaker 1: could be surrounded by organized sound, moving with other bodies,
• 41:36
  Speaker 1: hearing repeated patterns, breathing inside smoke and odor, watching images
• 41:41
  Speaker 1: and performers, and anticipating the presence of divine forces. Ritual
• 41:46
  Speaker 1: worked across sensory channels at once. That convergence, not any
• 41:50
  Speaker 1: single drumbeat, plant, or mirror, is where the physiology becomes
• 41:54
  Speaker 1: most interesting. One of the easiest mistakes to make when
• 41:57
  Speaker 1: discussing Central Mexican religion is to jump directly from codices
• 42:01
  Speaker 1: to human sacrifice as though every ritual ultimately.
• 42:05
  Speaker 2: Existed to kill somebody.
• 42:07
  Speaker 1: The historical reality is much more complicated because blood could
• 42:11
  Speaker 1: enter ritual through self-sacrifice, in which participants intentionally wounded themselves
• 42:16
  Speaker 1: and offered their own blood. Mesoamerican traditions of auto-sacrifice long
• 42:21
  Speaker 1: predated the Mexica, appearing in multiple societies across centuries, and
• 42:25
  Speaker 1: the logic cannot be understood simply as a lesser version
• 42:29
  Speaker 1: of human sacrifice. That distinction matters because self-bloodletting changes the
• 42:34
  Speaker 1: relationship between practitioner and offering. The person is simultaneously priest, participant,
• 42:41
  Speaker 1: and source of sacrificial material. So the body itself becomes
• 42:45
  Speaker 1: one of the ritual objects through which the offering is produced.
• 42:49
  Speaker 1: Modern observers tend to view blood almost exclusively through biomedical categories.
• 42:54
  Speaker 1: Blood is plasma, red cells, white cells, platelets, proteins, glucose, hormones, gases,
• 43:02
  Speaker 1: and waste products circling through vessels. All of that is
• 43:07
  Speaker 1: scientifically correct, but long before anyone knew what a red
• 43:10
  Speaker 1: blood cell was, humans understood the basic relationship between blood
• 43:14
  Speaker 1: and life because.
• 43:15
  Speaker 2: A wounded animal loses blood and weakens.
• 43:18
  Speaker 1: A badly wounded person can lose enough blood to die,
• 43:21
  Speaker 1: menstrual blood appears without visible injury, childbirth and warfare can
• 43:25
  Speaker 1: produce large quantities of blood, blood coagulates outside the body,
• 43:29
  Speaker 1: and fresh blood is warm, making it one of the
• 43:31
  Speaker 1: most obvious substances through which life appears capable of leaving
• 43:35
  Speaker 1: the organism. It is therefore hardly surprising that cultures around
• 43:39
  Speaker 1: the world turned blood into ritual substance. In Nawa'u ritual context,
• 43:45
  Speaker 1: the heart and blood acquired particularly powerful significance. The heart, Yolo'u,
• 43:50
  Speaker 1: was not simply the mechanical pump described in modern cardiology.
• 43:55
  Speaker 1: As we discussed in Part 1, Nawa'u language connected the
• 43:58
  Speaker 1: heart with interior states, identity, courage, and preciousness. Blood, likewise,
• 44:04
  Speaker 1: could become something offered precisely because it belongs so intimately
• 44:08
  Speaker 1: to life. Once we understand that, human sacrifice becomes easier
• 44:12
  Speaker 1: to analyze historically, although no less violent. There are two
• 44:17
  Speaker 1: dishonest ways of talking about Mexican human sacrifice. The first
• 44:21
  Speaker 1: is the sensationalist version in which the Mexica becomes uniquely
• 44:24
  Speaker 1: bloodthirsty monsters whose entire civilization existed to rip out hearts,
• 44:29
  Speaker 1: while the second is the apologetic version in which historians
• 44:33
  Speaker 1: become so uncomfortable that with colonial exaggeration that the violence
• 44:37
  Speaker 1: is minimized until sacrifice almost disappears. Neither approach is useful
• 44:42
  Speaker 1: because human sacrifice happened. The documented sources describe it, and
• 44:46
  Speaker 1: archaeology independently supports it. Isotopic and bioarchaeological work on sacrificial
• 44:52
  Speaker 1: remains from Tenochtitlan and Tlalocco has identified victims with diverse
• 44:57
  Speaker 1: residential histories, including locals, long-term residents, and non-locals whose origins
• 45:02
  Speaker 1: can be connected with regions incorporated into or subjugated by
• 45:06
  Speaker 1: the Triple Alliance, which fits documentary evidence that captives, enslaved people,
• 45:12
  Speaker 1: and other designated individuals could enter sacrificial systems. The Florentine
• 45:17
  Speaker 1: Codex's book, too, describes multiple festival sacrifices in extraordinary detail.
• 45:23
  Speaker 1: During ceremonies connected with the rain deities, for example, children
• 45:26
  Speaker 1: were sacrificed on mountains. and their tears could themselves be
• 45:30
  Speaker 1: interpreted as signs of concerning future rainfall. Captives were killed
• 45:34
  Speaker 1: in other ceremonies, and heart extraction appears repeatedly in the accounts.
• 45:39
  Speaker 1: Those descriptions are horrifying to a modern reader because they
• 45:42
  Speaker 1: describe real killing, and we should allow them to remain horrifying,
• 45:46
  Speaker 1: but the historian still has another job after acknowledging the violence.
• 45:51
  Speaker 1: We also have to understand why particular sacrificial actions could
• 45:54
  Speaker 1: make sense within the cosmology and political order of the
• 45:57
  Speaker 1: people performing them. And this is where the language of
• 46:00
  Speaker 1: cosmic reciprocity becomes useful as one explanatory layer rather than
• 46:05
  Speaker 1: as a magic key that explains every killing. Now while
• 46:09
  Speaker 1: religious narratives repeatedly present life as dependent upon exchanges among humans, gods, sun, earth, rain, agriculture,
• 46:18
  Speaker 1: and death, yet sacrifice also intersected with warfare, captive-taking, imperial expansion,
• 46:25
  Speaker 1: social hierarchy festival calendars and the public display of state
• 46:29
  Speaker 1: power so reducing every victim to the single idea of
• 46:33
  Speaker 1: feeding the gods would flatten a system that operated at
• 46:36
  Speaker 1: several levels simultaneously within particular ceremonies the sacrificial body could
• 46:42
  Speaker 1: therefore become more than a victim in the ritual imagination
• 46:46
  Speaker 1: functioning as a medium through which exchange obligation warfare status
• 46:51
  Speaker 1: political authority and divine relationship were made materially visible None
• 46:56
  Speaker 1: of that makes the killing morally acceptable by modern standards
• 46:59
  Speaker 1: because explanation is not justification and understanding a theology does
• 47:04
  Speaker 1: not require.
• 47:04
  Speaker 2: Adopting its ethics.
• 47:07
  Speaker 1: This is important because discussion of ancient sacrifice often collapses
• 47:11
  Speaker 1: those two things. Either we condemn it so quickly we
• 47:14
  Speaker 1: stop explaining it or we explain it so sympathetically that
• 47:18
  Speaker 1: we appear to excuse it. We can do both jobs
• 47:21
  Speaker 1: at once by historically understanding the system while still recognizing
• 47:25
  Speaker 1: the violence without euphemism. The heart itself is central to
• 47:29
  Speaker 1: this because it concentrates several layers of meaning at once. Biologically,
• 47:34
  Speaker 1: it is necessary for circulation. Visibly, it beats. Physically, it
• 47:39
  Speaker 1: is warm and full of blood. And linguistically, it participates
• 47:42
  Speaker 1: in concepts of interiority and value. Ritually removing it places
• 47:47
  Speaker 1: the most obvious moving organ of life directly into sacrificial exchange.
• 47:53
  Speaker 1: To the modern neuroscientific mind, consciousness resides overwhelmingly in the
• 47:57
  Speaker 1: brain rather.
• 47:58
  Speaker 2: Than the heart.
• 47:59
  Speaker 1: To the Nahuatl virtual imagination, the heart could nevertheless serve
• 48:03
  Speaker 1: as a powerful center of human life. Again, biological mechanism
• 48:08
  Speaker 1: and cultural meaning diverge without becoming mutually exclusive levels of explanation.
• 48:13
  Speaker 2: But then death itself introduces another surprise.
• 48:16
  Speaker 1: Because if Christian assumptions have trained us to expect a
• 48:18
  Speaker 1: moral sorting system after death, Nahuatl traditions often organize the
• 48:23
  Speaker 1: dead according to something else entirely, One of the most
• 48:27
  Speaker 1: important corrections to popular descriptions of Nahuatl religion concerns the afterlife,
• 48:32
  Speaker 1: because the dead were not simply imagined as entering one
• 48:35
  Speaker 1: generic underworld, nor were they sorted according to a Christian-style
• 48:38
  Speaker 1: judgment in which morally good people enter heaven and morally
• 48:42
  Speaker 1: bad people enter hell. Early colonial sources, especially the Sahagintai material,
• 48:48
  Speaker 1: encouraged generations of scholars to describe a system in which
• 48:51
  Speaker 1: the manner of death played a major role in determining
• 48:54
  Speaker 1: post-mortem destinations. And that traditional model usually emphasized Mictlan for
• 48:59
  Speaker 1: many ordinary deaths, Tonantio Aichen or the House of the
• 49:03
  Speaker 1: Sun for prestigious deaths associated with warfare, sacrifice, and childbirth,
• 49:08
  Speaker 1: and a special destination for deceased infants. That model remains
• 49:12
  Speaker 1: historically important because it reflects what some of our most
• 49:15
  Speaker 1: influential colonial sources actually say.
• 49:18
  Speaker 2: But a major 2026 reenactment.
• 49:20
  Speaker 1: By Julia Magichek, Roberto Martinez, and colleagues argues that scholars
• 49:24
  Speaker 1: have treated what they call the Sahagintine paradigm far too literally.
• 49:29
  Speaker 1: Their argument is not merely that the old four-destination diagram
• 49:33
  Speaker 1: needs a few footnotes. They contend that the familiar picture
• 49:37
  Speaker 1: of several fixed, vertically stacked afterlife regions is itself misleading
• 49:42
  Speaker 1: because now our other worlds are better approached as conceptual
• 49:45
  Speaker 1: domains involving space, time, divine beings, actions and transformations rather
• 49:52
  Speaker 1: than as supernatural countries sitting permanently above or below one another.
• 49:57
  Speaker 1: The same study proposes an especially provocative framework in which
• 50:01
  Speaker 1: the wider supernatural dimension can be understood through two broad
• 50:04
  Speaker 1: relational principles marked by the numbers 8 and 9 In
• 50:09
  Speaker 1: their reconstruction, 8 characterizes domains of communication or contact in
• 50:14
  Speaker 1: which humans, gods, and the dead can interact through sacrifice, dreams,
• 50:18
  Speaker 1: supernatural journeys, and other forms of exchange, while 9 characterizes
• 50:23
  Speaker 1: a more remote domain of destruction, deactivation, and transformation in
• 50:28
  Speaker 1: which identity is broken down and reorganized into new forms
• 50:31
  Speaker 1: of life. That does not mean that every older name
• 50:34
  Speaker 1: suddenly disappears. What changes is the assumption that each name
• 50:38
  Speaker 1: has a designated one fixed location on a cosmic map.
• 50:43
  Speaker 1: The newer model fits the argument of the episode almost
• 50:46
  Speaker 1: uncomfortably well. Because once the Afterworlds are treated as domains
• 50:50
  Speaker 1: of relationship and transformation, rather than as four supernatural boxes,
• 50:54
  Speaker 1: death becomes another example of the same relational logic we
• 50:58
  Speaker 1: have been following through calendar, body, omen, dream, mirror, and ritual.
• 51:03
  Speaker 1: The old textbook model remains useful for explaining how Sahagin's
• 51:07
  Speaker 1: material was historically read, but the newer scholarship warns us
• 51:10
  Speaker 1: not to confuse that colonial synthesis with the full complexity
• 51:14
  Speaker 1: of pre-contact Nahuatl thought. This also means that familiar statements
• 51:19
  Speaker 1: about matter of death need to be handled with care,
• 51:22
  Speaker 1: rather than simply repeated as universal rules. Sahagintine sources and
• 51:27
  Speaker 1: the scholarship built from them associate water-related deaths with Tolucan.
• 51:31
  Speaker 1: warriors and certain sacrificial victims with solo relationships, and women
• 51:35
  Speaker 1: who died during childbirth with a powerful post-mortem status that
• 51:39
  Speaker 1: later scholarship often discusses through C.
• 51:42
  Speaker 2: Guadateo.
• 51:43
  Speaker 1: Those traditions are real parts of the documentary record, but
• 51:47
  Speaker 1: the 2026 reassessment cautions us against imagining that every individual
• 51:51
  Speaker 1: was mechanically assigned to one of four destinations according to
• 51:56
  Speaker 1: a simple decision tree. Within the traditional Sagantine picture, the
• 52:00
  Speaker 1: difference from Christian moral sorting remains striking because two people
• 52:04
  Speaker 1: could live nearly identical lives, yet be imagined as entering
• 52:07
  Speaker 1: different post-partum relationships if one died from an ordinary illness
• 52:11
  Speaker 1: while another drowned, not because one was morally superior, but
• 52:14
  Speaker 1: because the circumstances of death connected each person with different
• 52:18
  Speaker 1: divine and cosmological forces. Earlier scholarship likewise describes warriors accompanying
• 52:24
  Speaker 1: the sun and later appearing in forms associated with brilliantly
• 52:27
  Speaker 1: colored birds or butterflies. while women who died in childbirth
• 52:31
  Speaker 1: could be conceptualized through imagery of combat and transformed into
• 52:35
  Speaker 1: terrifying and powerful post-mortem female beings, showing again that the
• 52:40
  Speaker 1: category of death could be shaped by the manner in
• 52:42
  Speaker 1: which life ended. The underlying principle remains useful as long
• 52:46
  Speaker 1: as we do not mistake it for a rigid universal formula.
• 52:50
  Speaker 1: Drowning is not merely respiratory failure, but can become death
• 52:53
  Speaker 1: through water. Death in battle is not merely hemorrhage or trauma,
• 52:57
  Speaker 1: but can become death through warfare, and death during childbirth
• 53:01
  Speaker 1: is not merely obstetric catastrophe, but can become connected with
• 53:04
  Speaker 1: reproductive struggle, danger, and female sacred power. Modern medicine identifies
• 53:10
  Speaker 1: mechanisms while Nahuatl cosmology identifies relationships, and the two levels
• 53:15
  Speaker 1: of explanation can coexist historically without being confused. Mitglenn presents
• 53:20
  Speaker 1: the same problem of translation because it has so often
• 53:23
  Speaker 1: been been rendered as an Aztec hell, even though the
• 53:26
  Speaker 1: older Sahagantine material does not primarily present it as a
• 53:30
  Speaker 1: place where morally bad people are punished for sin. Traditional
• 53:34
  Speaker 1: reconstructions describe a difficult journey lasting approximately four years, and
• 53:39
  Speaker 1: involving dangerous passages before the dead reach the deeper domain
• 53:42
  Speaker 1: associated with Mekantikuli and Mikdikasiwato, yet the 2026 reassessment goes
• 53:48
  Speaker 1: further by distinguishing the transient journeying domain, sometimes called Miklan,
• 53:54
  Speaker 1: from Mictlan as the more remote domain of the Lord
• 53:56
  Speaker 1: of the Dead, which helps explain why apparently contradictory descriptions
• 54:01
  Speaker 1: can coexist in the source record. That distinction matters because
• 54:04
  Speaker 1: difficulty does not automatically equal moral punishment. A movement through
• 54:09
  Speaker 1: dangerous otherworldly conditions does not require anything resembling the Christian
• 54:13
  Speaker 1: doctrine of hell. A journey of death can be frightening
• 54:16
  Speaker 1: because death itself is transformation. While the newest scholarship suggests
• 54:20
  Speaker 1: that some of these journeys are better understood as movement
• 54:23
  Speaker 1: among overlapping time spaces and conceptual domains than as travel
• 54:27
  Speaker 1: down a literal stack of subterranean floors. Once that is
• 54:31
  Speaker 1: placed beside the distributed person we developed in Part 1,
• 54:35
  Speaker 1: the afterlife becomes even more interesting, because if personhood is
• 54:38
  Speaker 1: constituted through several interacting relationships rather than one immortal soul object,
• 54:44
  Speaker 1: death does not necessarily require one indivisible spiritual person to
• 54:49
  Speaker 1: travel intact from earth into a single eternal destination. The
• 54:54
  Speaker 1: body decays while social identity remains in memory. Clingical identity
• 54:58
  Speaker 1: may retain ritual significance, and particular vital or animating relationships
• 55:03
  Speaker 1: can be assigned different trajectories within traditional interpretation. So the
• 55:08
  Speaker 1: dead person changes category, and death can be understood as
• 55:11
  Speaker 1: a redistribution and transformation of relationship, rather than simply as
• 55:16
  Speaker 1: the moment when one western-style soul leaves one biological body.
• 55:21
  Speaker 1: There is also a second correction we now need to make,
• 55:24
  Speaker 1: because textual descriptions of the afterlife are only one side
• 55:27
  Speaker 1: of death. Roberto Martinez-Gonzalez's 2026 study of ancient Nahuatl funerary
• 55:33
  Speaker 1: practice deliberately compares historical accounts with archaeological evidence and focuses
• 55:39
  Speaker 1: on three practices that can actually be tested materially. Placing
• 55:44
  Speaker 1: greenstone or jade beads in the mouth of the dead,
• 55:47
  Speaker 1: depositing dog remains in burials, and placing food or other
• 55:51
  Speaker 1: objects with bodies. The archaeological record does confirm all three,
• 55:55
  Speaker 1: but much less frequently than a literal reading of the
• 55:58
  Speaker 1: documentary sources might lead us to expect. Martinez-Gonzalez therefore proposes
• 56:03
  Speaker 1: that some of the funerary procedures preserved in written accounts
• 56:07
  Speaker 1: may represent idolized or socially restricted ceremonies rather than a
• 56:11
  Speaker 1: universal script followed for every deceased person. That is exactly
• 56:16
  Speaker 1: the kind of correction this series needs. A colonial description
• 56:19
  Speaker 1: may preserve genuine Nawa ideas without describing what every household
• 56:24
  Speaker 1: actually did, and archaeology can sometimes show us the difference
• 56:27
  Speaker 1: between an ideal ritual model and ordinary practice. At this point,
• 56:32
  Speaker 1: we can finally bring the scientific side of the project
• 56:35
  Speaker 1: together without committing the mistake we have been avoiding from
• 56:38
  Speaker 1: the beginning. The Nawa do not understand serotonin receptors. did
• 56:43
  Speaker 1: not know that scopolamine blocks muscarinic acetylcholine receptors, or that
• 56:47
  Speaker 1: mescaline acts substantially through serotonergic signaling. It did not possess EEG, MRI, endocrinology,
• 56:55
  Speaker 1: or autonomic neuroscience. But none of that diminishes what they
• 56:58
  Speaker 1: discovered experientially about ways particular practices and substances could alter
• 57:03
  Speaker 1: human experience. A culture does not need a receptor map
• 57:07
  Speaker 1: to learn that peyote changes perceptions. It does not need
• 57:11
  Speaker 1: REM sleep theory to learn that dreams feel real. It
• 57:14
  Speaker 1: does not need a sympathetic nervous system diagram to discover
• 57:18
  Speaker 1: that terror changes heartbeat and breathing. It does not need
• 57:21
  Speaker 1: visual neuroscience to discover that darkness and reflective surfaces create
• 57:25
  Speaker 1: strange experiences. It does not need pain science to discover
• 57:29
  Speaker 1: that controlled suffering can change attention. Human beings encounter those
• 57:33
  Speaker 1: phenomena first and explain their mechanisms later. Modern neuroscience now
• 57:38
  Speaker 1: allows us to understand some of the machinery. Serotonergic psychedelics
• 57:43
  Speaker 1: change large-scale patterns of neurocommunication and sensory integration. Mescaline affects
• 57:48
  Speaker 1: serotonergic signaling and produces sustained changes in perception and cognition.
• 57:54
  Speaker 1: Deuteroclass antimuscarinic compounds can produce delirium by disrupting cholinergic systems
• 57:59
  Speaker 1: necessary for attention and memory. Severe sleep deprivation can produce
• 58:04
  Speaker 1: perceptual distortions and hallucinations. Breathing rhythm interacts with brainstem and
• 58:10
  Speaker 1: emotion-related neural systems. Dim mirror gazing can produce dramatic face
• 58:14
  Speaker 1: distortions even in healthy volunteers. Once those mechanisms are placed together,
• 58:20
  Speaker 1: the ritual environment begins looking extraordinarily powerful from a physiological perspective.
• 58:26
  Speaker 1: But this is where I want to resist the phrase
• 58:28
  Speaker 1: ancient neuroscience. That phrase sounds exciting precisely because it collapses
• 58:33
  Speaker 1: the distance between ancient practice and modern explanations. But it
• 58:37
  Speaker 1: is historically wrong because neuroscience names a specific scientific tradition
• 58:42
  Speaker 1: involving anatomical, physiological, chemical, and experimental investigation of the nervous system.
• 58:49
  Speaker 1: A tradition the Nawa did not possess even though they
• 58:51
  Speaker 1: accumulated extensive practical knowledge about human experience in altered states.
• 58:57
  Speaker 1: That distinction is important because human cultures can discover reliable
• 59:01
  Speaker 1: techniques without understanding the mechanisms. People fermented alcohol thousands of
• 59:07
  Speaker 1: years before microbiology. Sailors navigate. by stars before astrophysics, and
• 59:12
  Speaker 1: herbalists used willow bark before anyone isolated salicylic acid. So
• 59:17
  Speaker 1: reliable practices clearly do not require a correct modern theory
• 59:21
  Speaker 1: of mechanism. Likewise, ritual traditions could learn that fasting, darkness,
• 59:27
  Speaker 1: sleep loss, rhythmic repetition, psychoactive plants, mirrors, and pain altered
• 59:32
  Speaker 1: consciousness without knowing anything about cortical networks or neurotransmitters. In
• 59:38
  Speaker 1: that sense, ritual is less like primitive neuroscience and more
• 59:41
  Speaker 1: like empirical cultural technology. Because people perform a procedure, something happens,
• 59:47
  Speaker 1: the result is remembered and repeated, meaning it accumulates around
• 59:51
  Speaker 1: the experience, and over generations the technique can become tradition
• 59:55
  Speaker 1: before a culture develops or elaborates an explanation for why
• 59:58
  Speaker 1: it works. That explanation may involve gods, spirits, ancestors, fate,
• 1:00:04
  Speaker 1: or invisible worlds rather than neurons. But the altered state
• 1:00:08
  Speaker 1: can still be experientially and physiologically real even when the
• 1:00:12
  Speaker 1: cultural explanation for it is not a scientific account of mechanism.
• 1:00:17
  Speaker 1: This is where reductive skepticism gets itself into trouble.
• 1:00:21
  Speaker 2: If you say the experience.
• 1:00:22
  Speaker 1: Has a neurological mechanism and therefore it was fake, you
• 1:00:26
  Speaker 1: misunderstand what neuroscience actually explains. Every experience has a neurological mechanism,
• 1:00:32
  Speaker 1: whether we are talking about love, grief, music, fear, religious ecstasy,
• 1:00:37
  Speaker 1: seeing your mother, or recognizing your own name. And finding
• 1:00:41
  Speaker 1: a neural correlate does not make any of those experiences unreal.
• 1:00:45
  Speaker 1: It tells us how the biological organism becomes capable of
• 1:00:49
  Speaker 1: having it. The unresolved question concerns interpretation, because if somebody
• 1:00:54
  Speaker 1: sees a frightening face emerge in a black mirror, neuroscience
• 1:00:57
  Speaker 1: may explain the visual instability. It cannot prove whether Tezcatlipoca
• 1:01:01
  Speaker 1: was present, because that claim belongs to a metaphysical and
• 1:01:05
  Speaker 1: cultural level that a laboratory measure cannot directly adjudicate. If
• 1:01:09
  Speaker 1: somebody experiences complex imagery after ingesting peyote, pharmacology can explain
• 1:01:14
  Speaker 1: why perception changed. It cannot decide the religious meaning of
• 1:01:18
  Speaker 1: the vision. Science is extremely good at mechanisms, but it
• 1:01:21
  Speaker 1: becomes much less capable once the question becomes what an
• 1:01:25
  Speaker 1: experience should mean to a human being. because cultures answer
• 1:01:29
  Speaker 1: that question and Nahuatl culture devolved extraordinarily elaborate answers of
• 1:01:33
  Speaker 1: its own. We can now return to the question that
• 1:01:36
  Speaker 1: opened the entire two-part series. If we ask whether the
• 1:01:39
  Speaker 1: Nahuatl practice magic and we use magic as a broad
• 1:01:43
  Speaker 1: modern comparative category, then the answer is obviously yes, because
• 1:01:47
  Speaker 1: they practice forms of divination, interpreted omens, recognized specialists feared
• 1:01:52
  Speaker 1: or respected for supernatural powers, used ritual plants, performed the bloodletting,
• 1:01:57
  Speaker 1: worked with sacred images and objects, used calendrical systems to
• 1:02:01
  Speaker 1: interpret human destiny, preserved traditions surrounding transformation and Nahuali, and
• 1:02:06
  Speaker 1: conducted rituals directed toward rain, agriculture, warfare, health, and divine powers.
• 1:02:12
  Speaker 1: From a modern comparative religion perspective, enormous portions of that
• 1:02:16
  Speaker 1: material can reasonably be studied under the history of magic.
• 1:02:20
  Speaker 1: But if we ask whether Nahual society possessed one indigenous
• 1:02:23
  Speaker 1: category exactly equivalent to our modern umbrella word magic, the
• 1:02:27
  Speaker 1: answer becomes less certain. The word magic itself carries thousands
• 1:02:31
  Speaker 1: of years of European intellectual baggage accumulated through Greco-Roman religion,
• 1:02:36
  Speaker 1: Christian demonology, medieval sorcery law, Renaissance natural magic, ceremonial magic,
• 1:02:42
  Speaker 1: stage magic, modern occultism, and anthropology. So every time we
• 1:02:47
  Speaker 1: place a foreign religious practice into that category, we risk
• 1:02:50
  Speaker 1: turning difference into familiarity before we have actually understood the
• 1:02:54
  Speaker 1: practice on its own terms. A Nahuatl healer is not
• 1:02:58
  Speaker 1: automatically a witch. A Tonopukwai is not automatically an astrologer.
• 1:03:03
  Speaker 1: A priest using incense is not automatically a ceremonial magician.
• 1:03:07
  Speaker 1: A person connected with Nahuatl traditions is not simply a shapeshifter.
• 1:03:11
  Speaker 1: An obsidian mirror is not simply a black scrying mirror
• 1:03:14
  Speaker 1: from a European grimoire, because the comparative category becomes useful
• 1:03:18
  Speaker 1: only after the indigenous practice has been understood on its
• 1:03:22
  Speaker 1: own terms. Which brings us back to the methodological rule
• 1:03:26
  Speaker 1: with which Part 1 began. Understanding the Nahuatl material first
• 1:03:30
  Speaker 1: and only, then begin making comparisons with other magical, religious,
• 1:03:34
  Speaker 1: or scientific systems. Once we follow that rule, the comparison
• 1:03:38
  Speaker 1: actually becomes better. Now we can compare obsidian mirror practices
• 1:03:43
  Speaker 1: with European scrying because we understand that they emerge from
• 1:03:46
  Speaker 1: different cosmologies. We can compare birth divination with astrology because
• 1:03:51
  Speaker 1: we understand that the Tonopahuali is not the zodiac. We
• 1:03:55
  Speaker 1: can compare ritual plants with psychedelic religion because we know
• 1:03:58
  Speaker 1: which plants contain which compounds and which claims remain uncertain.
• 1:04:03
  Speaker 1: We can compare ritual physiology with modern neuroscience because we
• 1:04:06
  Speaker 1: are not pretending that the Nahuatl secretly knew receptor pharmacology.
• 1:04:11
  Speaker 1: We can compare concepts of personhood across cultures without forcing tonali, heart, breath,
• 1:04:17
  Speaker 1: or nahuali into the vocabulary of chakras, astral bodies, or
• 1:04:21
  Speaker 1: Christian souls. The result may be less sensational than a
• 1:04:25
  Speaker 1: story about secret lost signs, but it is also far
• 1:04:28
  Speaker 1: stranger because the real historical systems resist the categories we
• 1:04:32
  Speaker 1: keep trying to impose on them. There is one subject
• 1:04:36
  Speaker 1: we have not discussed enough in Part 2, and that
• 1:04:39
  Speaker 1: absence has been deliberate because I wanted it to disappear
• 1:04:42
  Speaker 1: temporarily while we move through mirrors, plants, blood, and death.
• 1:04:47
  Speaker 1: Now the Codex returns, and with everything else in place,
• 1:04:50
  Speaker 1: we can see it differently. At the beginning of Part 1,
• 1:04:53
  Speaker 1: the Codex looks like an ancient illustrated book. By the
• 1:04:56
  Speaker 1: end of Part 2, I think we can see that
• 1:04:58
  Speaker 1: some manuscripts belong inside a much larger category as technologies
• 1:05:03
  Speaker 1: for organizing relationships because a total non-metal organizes numbered days, signs,
• 1:05:08
  Speaker 1: and divine patrons. A ritual manuscript organizes gods, costumes, directional relationships, offerings,
• 1:05:14
  Speaker 1: and time. A historical manuscript organizes rulers, migrations, and conquest.
• 1:05:19
  Speaker 1: And a medicinal text organizes plants, Systems and Treatments The
• 1:05:24
  Speaker 1: Codex does something human brains have always done but cannot
• 1:05:27
  Speaker 1: do perfectly on their own. It moves memory outside the body.
• 1:05:32
  Speaker 1: Once knowledge exists on a durable external surface, an individual
• 1:05:36
  Speaker 1: human being no longer has to contain the whole system internally,
• 1:05:40
  Speaker 1: because the manuscript can function as a form of collective
• 1:05:43
  Speaker 1: memory that outlives any one specialist. And that is true
• 1:05:47
  Speaker 1: whether the information is scientific, administrative, religious, or divinatory. Writing
• 1:05:53
  Speaker 1: is one of humanity's great consciousness technologies precisely because it
• 1:05:57
  Speaker 1: allows thought to survive the thinker. The 2026 reinterpretation of
• 1:06:02
  Speaker 1: the Codex Cospi makes that point even stronger because it
• 1:06:05
  Speaker 1: suggests that a divinatory manuscript could participate not only in
• 1:06:09
  Speaker 1: identifying a condition, but in prescribing a response. On the reverse,
• 1:06:14
  Speaker 1: offerings represented beside divine effigies include blood, aromatic substances, coloring materials,
• 1:06:21
  Speaker 1: and precious gods. If Dupe Garcia's reading is correct, the
• 1:06:25
  Speaker 1: Codex could help organize the movement from prognosis to ritual action.
• 1:06:29
  Speaker 1: Something is divined, the situation is classified, and the manuscript
• 1:06:33
  Speaker 1: preserves the offerings or procedures through which people attempt to
• 1:06:36
  Speaker 1: answer it. The book therefore becomes more than stored information.
• 1:06:41
  Speaker 1: In use, it can become part of a feedback loop
• 1:06:44
  Speaker 1: between interpretation and action. That also helps us understand why
• 1:06:48
  Speaker 1: the materiality surrounding writing mattered. paper and central Mexican religion
• 1:06:53
  Speaker 1: was not confined to the modern category of pages. Historical
• 1:06:57
  Speaker 1: evidence and later indigenous continuities preserve ritual paper as something
• 1:07:01
  Speaker 1: that could be cut, dressed onto divine figures, placed on altars,
• 1:07:06
  Speaker 1: and marked with sacrificial substances. We should be careful not
• 1:07:09
  Speaker 1: to project a modern Huastica paper ceremony unchanged into pre-conquest Tenochtitlan.
• 1:07:15
  Speaker 1: But the broader lesson is secure. Graphic media and ritual
• 1:07:19
  Speaker 1: objects did not always occupy separate worlds. A surface could
• 1:07:23
  Speaker 1: represent something, record something, and participate materially in ceremonial action.
• 1:07:29
  Speaker 1: That gives us a final way of understanding why destroying
• 1:07:31
  Speaker 1: indigenous manuscripts was so devastating. Destroying a codex was not
• 1:07:36
  Speaker 1: merely destroying a religious painting. Depending upon the manuscript, it
• 1:07:40
  Speaker 1: could mean destroying records of ancestry, history, law, land, tribute, medicine, ritual,
• 1:07:46
  Speaker 1: and collegial knowledge. It could erase part of the cultural
• 1:07:49
  Speaker 1: memory through which a community understood itself. Yet enough survived,
• 1:07:54
  Speaker 1: and enough was recreated under colonial conditions, that we can
• 1:07:57
  Speaker 1: still reconstruct pieces of the system centuries later. That is
• 1:08:01
  Speaker 1: why these books matter, because they are fragments of a
• 1:08:04
  Speaker 1: cognitive world that conquest attempted to transform, but never completely erased.
• 1:08:10
  Speaker 1: We began this series by asking what Mexican and Nahuatl
• 1:08:12
  Speaker 1: codices actually were. The answers turned out to be much
• 1:08:16
  Speaker 1: larger than expected. We found books that were not simply books,
• 1:08:19
  Speaker 1: images that were not simply images, calendars that were not
• 1:08:22
  Speaker 1: simply calendars, and bodies that were not simply bodies. The
• 1:08:26
  Speaker 1: Nawa manuscript could operate through painting, number, language, spatial relationship,
• 1:08:31
  Speaker 1: and ritual association simultaneously. The ritual calendar could turn time
• 1:08:36
  Speaker 1: itself into a field of qualitative relationships. The day of
• 1:08:40
  Speaker 1: birth could place an individual inside that field. Tonali could
• 1:08:44
  Speaker 1: connect birth, heat, sun, vitality, and destiny with without fitting
• 1:08:48
  Speaker 1: neatly into the Christian category of soul. The heart, blood,
• 1:08:52
  Speaker 1: and breath could participate in personhood while remaining physical realities.
• 1:08:56
  Speaker 1: Omens could transform anomalies in the environment into intoxication.
• 1:09:00
  Speaker 2: Information.
• 1:09:01
  Speaker 1: Dreams could destabilize the boundary between ordinary identity and other
• 1:09:05
  Speaker 1: forms of being. Why Nawali traditions extended the problem of
• 1:09:09
  Speaker 1: personhood beyond the visible body. Part two then changed the
• 1:09:12
  Speaker 1: question from interpretation to the deliberate manipulation of perception. Instead
• 1:09:17
  Speaker 1: of asking how hidden information was interpreted, When it appeared,
• 1:09:21
  Speaker 1: we asked what happens when human beings deliberately construct conditions
• 1:09:24
  Speaker 1: under which ordinary perception becomes unstable. That led us back
• 1:09:28
  Speaker 1: to the black mirror of Tezcatlipoca. Obsidian gave us an
• 1:09:32
  Speaker 1: object capable of reflecting the world while swallowing most of
• 1:09:35
  Speaker 1: the light falling into it. And modern psychology showed us
• 1:09:39
  Speaker 1: that prolonged mirror gazing under reduced illumination can genuinely produce
• 1:09:43
  Speaker 1: startling visual distortions. Ancient Mexican evidence showed that obsidian mirrors
• 1:09:48
  Speaker 1: entered divinatory contexts and became inseparable from one of the
• 1:09:52
  Speaker 1: most complex gods in central Mexican religion. Then modern geochemistry
• 1:09:57
  Speaker 1: gave us the physical connection nobody needed to invent. A
• 1:10:00
  Speaker 1: Mexican obsidian mirror associated with John Dee really was made
• 1:10:04
  Speaker 1: from Mexican obsidian and has been geochemically traced to the
• 1:10:08
  Speaker 1: Pachuca source, meaning that an object belonging to an indigenous
• 1:10:11
  Speaker 1: American mirror tradition physically entered the world of European Renaissance occultism.
• 1:10:16
  Speaker 1: Plants gave us another doorway into the same problem by
• 1:10:19
  Speaker 1: changing perception through chemistry rather than reflective ambiguity. Ololiloqui involved
• 1:10:25
  Speaker 1: psychoactive ergoline alkaloids, peyote-contained mescaline, and psilocybin-containing mushrooms, and psilocybin-containing
• 1:10:33
  Speaker 1: mushrooms could profoundly alter sensory processing and internally generated imagery.
• 1:10:38
  Speaker 1: The Torah demonstrated that not every visionary plant belongs to
• 1:10:41
  Speaker 1: the same pharmacological class. because anticholinergic delirium can destroy the
• 1:10:46
  Speaker 1: boundary between hallucination and perceived reality in a way very
• 1:10:50
  Speaker 1: different from classical psychedelics. Ya'utli reminded us not to label
• 1:10:55
  Speaker 1: every aromatic ritual plant as psychedelic merely because we want
• 1:10:59
  Speaker 1: the ancient world to be stranger than the sources allow.
• 1:11:02
  Speaker 1: Then the entire ritual environment became visible as a technology
• 1:11:05
  Speaker 1: of attention in which fasting, night vigil, rhythm, breathing, darkness, smoke, scent, pain, blood, expectation, movement,
• 1:11:15
  Speaker 1: and in some contexts, psychoactive chemistry could converge. None of
• 1:11:20
  Speaker 1: those mechanisms require supernatural intervention in order to alter human consciousness,
• 1:11:25
  Speaker 1: but none of their neurological explanations automatically eliminates religious meaning either.
• 1:11:31
  Speaker 1: That may be the most important thing we have learned.
• 1:11:34
  Speaker 1: For too long, discussions of religion and altered states have
• 1:11:36
  Speaker 1: been trapped between two childish extremes. One side says that
• 1:11:40
  Speaker 1: because an experience can be explained neurologically, it must therefore
• 1:11:44
  Speaker 1: be meaningless, while the other says that because an experience
• 1:11:47
  Speaker 1: feels profound, its supernatural interpretation must therefore be scientifically true,
• 1:11:52
  Speaker 1: yet neither conclusion follows from the evidence. The human brain
• 1:11:57
  Speaker 1: is the biological instrument through which every human experience occurs.
• 1:12:01
  Speaker 1: If a ritual changes the brain, that tells us the
• 1:12:03
  Speaker 1: ritual is doing something. It does not tell us what
• 1:12:06
  Speaker 1: metaphysical conclusion we are required to draw from it. The
• 1:12:10
  Speaker 1: Nawa interpreted altered experience through their own cosmology, while modern
• 1:12:14
  Speaker 1: neuroscience interprets underlying mechanisms through a scientific framework, and the
• 1:12:19
  Speaker 1: two systems answer different questions even when they are describing
• 1:12:22
  Speaker 1: different layers of the same human event. Death pushed that
• 1:12:26
  Speaker 1: separation even farther by showing how biological mechanisms and cultural
• 1:12:30
  Speaker 1: classification could diverge without either becoming irrelevant. Nawa afterlife traditions
• 1:12:36
  Speaker 1: often cared deeply about the manner of death, linking different
• 1:12:39
  Speaker 1: deaths with different destinations and divine relationships, rather than primarily
• 1:12:43
  Speaker 1: sorting people according to Christian moral judgment. Sacrifice placed the
• 1:12:48
  Speaker 1: body inside systems of reciprocity connecting humans with rain, warfare, agriculture, gods,
• 1:12:54
  Speaker 1: and cosmic continuity. The heart became more than a pump
• 1:12:57
  Speaker 1: without ceasing to be a pump. Blood became more than
• 1:13:00
  Speaker 1: tissue without ceasing to be tissue. A corpse became more
• 1:13:03
  Speaker 1: than dead biology because a culture had to determine what
• 1:13:06
  Speaker 1: death meant. When we place all that together, I do
• 1:13:09
  Speaker 1: not think the real story of Nahuatl cultism is that
• 1:13:12
  Speaker 1: an ancient civilization possessed a secret magical science modern people
• 1:13:16
  Speaker 1: somehow forgot. Because that story is too easy. The more
• 1:13:21
  Speaker 1: interesting story is that the Nahuatl constructed an intellectual world
• 1:13:24
  Speaker 1: in which relationships themselves could carry information. Between human and day,
• 1:13:30
  Speaker 1: birth and calendar, heat and life, heart and identity, animal
• 1:13:34
  Speaker 1: and place, dream and person, mirror and vision, plant in consciousness,
• 1:13:39
  Speaker 1: blood in offering, and manner of death in cosmic destination,
• 1:13:43
  Speaker 1: while the codices preserved and organized those relationships as part
• 1:13:47
  Speaker 1: of the machinery through which they became visible and interpretable.
• 1:13:51
  Speaker 1: That is what makes these manuscripts so difficult for us
• 1:13:54
  Speaker 1: to read, because we are often looking for sentences while
• 1:13:57
  Speaker 1: they are showing us structures, looking for isolated objects while
• 1:14:00
  Speaker 1: they are showing relationships, and asking whether something belongs to religion, medicine, magic,
• 1:14:06
  Speaker 1: or psychology, when the categories embodied by the sources do
• 1:14:09
  Speaker 1: not always accept those separations. And this is why I
• 1:14:13
  Speaker 1: think the most dangerous mistake we can make is assuming
• 1:14:16
  Speaker 1: that ancient people were either idiots or secret modern scientists.
• 1:14:20
  Speaker 1: They were neither, because they were human beings confronting the
• 1:14:23
  Speaker 1: same basic nervous system, the same vulnerability to death, the
• 1:14:27
  Speaker 1: same strange experience of dreaming, the same fear of darkness,
• 1:14:30
  Speaker 1: the same capacity for altered perception, the same need to
• 1:14:33
  Speaker 1: explain suffering, the same awareness that time moves toward death
• 1:14:37
  Speaker 1: and the same terrifying realization that the world contains more
• 1:14:41
  Speaker 1: information than one person can ever understand. They constructed answers
• 1:14:46
  Speaker 1: using the intellectual tools available to them. Just as we do,
• 1:14:50
  Speaker 1: although our tools now include microscopes, EEG, MRI, pharmacology, radiocarbon dating,
• 1:14:57
  Speaker 1: mass spectrometry, geochemical sourcing, archaeological and historical linguistics, all of
• 1:15:03
  Speaker 1: which allow us to see things that now are could
• 1:15:06
  Speaker 1: not have seen through their own methods. But the codices
• 1:15:09
  Speaker 1: allow us to see something our tools cannot recover by themselves.
• 1:15:13
  Speaker 1: They show us how another civilization decided what counted as meaningful.
• 1:15:17
  Speaker 1: And maybe that is ultimately why these manuscripts remain so unsettling.
• 1:15:22
  Speaker 1: They remain unsettling not because they reveal some lost secret technology,
• 1:15:25
  Speaker 1: or because there is a hidden Aztec grimoire waiting to
• 1:15:28
  Speaker 1: teach us how to summon Tezcatlapoca, but because once you
• 1:15:32
  Speaker 1: learn how another culture organized meaning, The categories you assumed
• 1:15:36
  Speaker 1: were natural begin looking historical, and boundaries between body and cosmos,
• 1:15:40
  Speaker 1: medicine and ritual, vision and hallucination, person and environment, and
• 1:15:45
  Speaker 1: even book and ritual begin to look far less permanent
• 1:15:48
  Speaker 1: than we usually imagine. We started this series staring at
• 1:15:51
  Speaker 1: strange painted pages and asking what the hell we are
• 1:15:54
  Speaker 1: looking at, and now I think we finally have an answer.
• 1:15:57
  Speaker 1: We were looking at fragments of a civilization teaching itself
• 1:16:01
  Speaker 1: how to read a world in which time, Bodies, animals, dreams, gods, plants, mirrors,
• 1:16:06
  Speaker 1: and death could all become forms of information. The question
• 1:16:10
  Speaker 1: was never simply whether that world was magical. The deeper
• 1:16:13
  Speaker 1: question was what those people thought reality was capable of communicating.
• 1:16:17
  Speaker 1: And after everything we have uncovered, I think the final
• 1:16:19
  Speaker 1: question has to turn back on us. Maybe the strangest
• 1:16:22
  Speaker 1: thing about the Nawa is not they believed the world
• 1:16:24
  Speaker 1: could speak through calendars, dreams, animals, bodies, and mirrors. Maybe
• 1:16:29
  Speaker 1: the strangest thing is how completely modern people have convinced
• 1:16:32
  Speaker 1: themselves that the world is silent unless information arrives in
• 1:16:35
  Speaker 1: a form our own culture has already decided how to measure.
• 1:16:39
  Speaker 1: And when you stare long enough into the black mirror,
• 1:16:42
  Speaker 1: eventually the question stops being what the Naha thought they
• 1:16:45
  Speaker 1: were seeing. The question becomes, what have we trained ourselves
• 1:16:49
  Speaker 1: not to see? And that's the end of another Occult Rejects.
• 1:16:53
  Speaker 1: Hope you all enjoyed, and until the next one.
