Carlos Castaneda’s The Teachings of Don Juan: A Yaqui Way of Knowledge (1968) is a book that blends anthropology, mysticism, and personal transformation. It presents what Castaneda claimed were his experiences apprenticing under a Yaqui shaman named Don Juan Matus, who introduced him to altered states of consciousness through the use of peyote and other psychoactive plants.
The book became highly influential, inspiring interest in shamanism, psychedelics, and alternative spiritual practices. It was initially accepted as a serious anthropological study, but over time, scholars began questioning its authenticity. Critics argue that Don Juan was likely a fictional character and that Castaneda fabricated much of his narrative, drawing from various indigenous traditions and philosophical ideas rather than actual fieldwork.
Despite its dubious academic credibility, The Teachings of Don Juan and Castaneda’s later works have remained popular, shaping the New Age movement and modern understandings of shamanism. His writings continue to attract both devoted followers and skeptics, making him one of the most controversial figures in modern spiritual literature.
