Artaud's experience with the primitive Tarahumara Indians in 1936 was a psychic ordeal and a spiritual revelation: "I have not come to visit the Tarahumara as a tourist but to regain a truth . . . I should go back to the source and expand my pre-conscious to the point where I could see myself evolve and desire. And Peyote led me to this point." This is the story of Artaud's visit, refracted through varying states of mind, and documenting his struggle to integrate an overwhelming mystical experience.
