The Teachings of Don Juan: A Yaqui Way of Knowledge was published by the University of California Press in 1968 as a work of anthropology, though many critics contend that it is a work of fiction. It was written by Carlos Castaneda and submitted as his Master’s thesis in the school of Anthropology. It purports to document the events that took place during an apprenticeship with a self-proclaimed Yaqui Indian Sorcerer, don Juan Matus from Sonora, Mexico between 1960 and 1965.
