The Teachings of Don Juan: A Yaqui Way of Knowledge

In the summer of 1960, Carlos Castaneda, an anthropology graduate student at the University of California, Los Angeles, travels to the American Southwest to research medicinal plants used by local Indians. At a bus station in a border town, a friend points out a white-haired old Indian said to be knowledgeable about peyote. Castaneda pretends expertise, but the old man, who introduces himself as Juan, sees through him. Castaneda tracks down don Juan's home and visits often, forming a friendship despite failing to discuss peyote. Those near don Juan consider him a brujo, a Spanish term for a medicine man or sorcerer. Don Juan reveals that he possesses secret knowledge learned from a teacher he calls his "benefactor" and that he has chosen Castaneda as his apprentice.

The book is divided into two parts. Part One presents Castaneda's field notes documenting his apprenticeship from 1961 to 1965, focusing on states of what he calls "nonordinary reality" induced by three hallucinogenic plants: peyote, Jimson weed (which don Juan calls "the devil's weed"), and a psychoactive mushroom. Part Two offers a structural analysis arguing that don Juan's teachings form a coherent system of logical thought.

Before agreeing to teach Castaneda, don Juan poses a test: Castaneda must find a specific "spot" on the porch floor where he feels naturally happy and strong. After hours of effort, Castaneda learns to perceive color changes at the periphery of his vision. He identifies two spots: one that fills him with dread, and one where he falls peacefully asleep. Don Juan confirms the latter as Castaneda's beneficial spot and the former as his "enemy," then agrees to begin the teachings.

Don Juan takes Castaneda to a gathering where another participant, a man named John, provides peyote buttons for Castaneda's first encounter with what don Juan calls "Mescalito," a power he describes as a protector and teacher contained in the peyote cactus. After chewing six buttons, Castaneda loses the ability to speak, perceives a dog as a transparent, glowing being, and enters a state of ecstatic play with the animal. Upon waking, the other men recount that Castaneda had chased the dog around the house, howling and barking. Don Juan insists the dog was Mescalito himself and declares Castaneda the "chosen man" he has been seeking, because Mescalito has never played with anyone before. Castaneda protests that fear makes him unsuited for the path, but don Juan tells him fear is the first natural enemy a man must overcome.

Don Juan formally begins the apprenticeship, introducing two "ally" powers that a sorcerer can tame and use. His benefactor was a diablero, a term among Sonoran Indians for a sorcerer capable of transforming into animals. The benefactor's ally resided in the devil's weed (Datura), which don Juan describes as powerful but dangerous: It distorts men and gives them a taste of power too soon. Don Juan's personal ally is the "little smoke" (humito), a hallucinogenic mushroom mixture. He tells Castaneda he will introduce both allies, but Castaneda can ultimately choose only one.

Castaneda begins work with the devil's weed, ingesting a potion made from the Datura root. Don Juan carves a protective figurine from the root and instructs Castaneda to replant a Datura shoot in a secret location. He also introduces the smoke mixture, whose ingredients require a yearlong preparation.

In a pivotal conversation, don Juan describes the four enemies on the path to becoming a "man of knowledge": Fear, which paralyzes; Clarity, which blinds with false confidence; Power, which corrupts; and Old Age, which saps the will. Each must be defeated in turn, though the last can only be fought away, never conquered.

During a peyote-gathering trip to Chihuahua, Castaneda encounters Mescalito a second time. He perceives a terrifying figure with a green, warty, peyote-like head and enormous eyes. The entity shows Castaneda a vision of himself as a stooped old man struck by sparks of light. Don Juan interprets this as a lesson, though Castaneda was too afraid to understand it fully.

Castaneda then learns the devil's weed's second portion, used for divination. Don Juan teaches him to catch two lizards and use them as instruments to perceive hidden knowledge. During the ritual, Castaneda experiences visions that he later realizes are narrations from the lizard on his shoulder, describing what its sister saw. Don Juan scolds him for mistaking the lizard's words for his own thoughts.

For the experience of bodily flight, Castaneda applies a Datura-based unguent to his body. He perceives himself soaring through the night sky with extraordinary freedom. He wakes naked in a field half a mile from don Juan's house. When Castaneda asks whether he really flew, don Juan insists the question is meaningless: A man who has taken the devil's weed flies "as such."

Castaneda's first experience with the smoke is terrifying. After inhaling, his body becomes numb, his hands pass through a solid pole, and he sinks into a wall as if it were sponge. Don Juan explains that the smoke literally took Castaneda's body, and that without don Juan to restore him, Castaneda would never have awakened.

During a four-day peyote ceremony in Chihuahua, Castaneda has his final encounters with Mescalito. On the third night, he asks Mescalito for a song, learns one, and sings it to the group. On the fourth night, Mescalito appears again, tells Castaneda its name, and shows him a vision of his father. Castaneda embraces the vision and confesses feelings he could never voice in ordinary life. Mescalito then appears as a luminous stick of light. Don Juan declares that Mescalito has fully accepted Castaneda and interprets the experience as a lesson: There is only one world for humans, and Castaneda's belief that he inhabits two worlds is vanity.

Through subsequent smoking sessions, don Juan teaches Castaneda to become a crow, guiding his perception through detailed verbal commands. During the final smoking experience, Castaneda perceives three silvery birds that don Juan identifies as crows and calls the "emissaries of your fate," whose flight patterns will foretell Castaneda's future.

The final major ordeal is not induced by any plant. Castaneda has been experiencing involuntary states of nonordinary reality, and don Juan concludes that someone has bewitched him and taken his soul. He instructs Castaneda to sit on his beneficial spot and maintain a fighting posture while don Juan investigates. After hours alone, a figure appears that looks like don Juan but moves with subtly wrong rhythms. Castaneda spends the night in terror, refusing to leave his spot and singing peyote songs. At dawn, he hurls a rock with a war cry that sends the figure staggering away. When the real don Juan emerges, Castaneda recognizes him instantly. Don Juan explains that Castaneda defeated a diablera, a female sorcerer who had assumed don Juan's form using a spirit helper.

Don Juan then describes the "crack between the worlds," a doorway between ordinary reality and the world of sorcerers that a man must reach through sheer will. He says he is no longer a warrior or a diablero: For him there is only traveling on paths that have heart, paths that strengthen and bring joy rather than weaken and destroy. During a later training exercise, Castaneda collapses in terror at a sound in the bushes. This is his last session. He believes he has succumbed to Fear, the first enemy of a man of knowledge. Don Juan views the withdrawal as a necessary recapitulation rather than a final break.

In Part Two, Castaneda presents a structural analysis identifying four main units in don Juan's knowledge: the concept of a "man of knowledge," the possession of an ally, the ally's rule (the fixed procedures governing how an ally is handled), and the corroboration of that rule through "special consensus," the systematic agreement a teacher provides regarding the elements of nonordinary reality. Without this consensus, the perceived experiences would remain purely personal and unverifiable. Castaneda concludes that don Juan's teachings form an internally cohesive system and that his apprenticeship had been only the beginning of a very long road.
