|A recluse whose biography has been the subject of dispute, Carlos Castaneda was a student of anthropology, who supposedly gave up his studies to study under Don Juan Matus, a Yaqui sorcerer. In TEACHINGS OF DON JUAN (1968), Castaneda tells how his mentor's teachings brought him to a higher level of awareness. At the end of the '60s, Castaneda's book captured the imagination of readers, many of whom were also seekers. His book has sold millions of copies worldwide, and Castaneda was awarded a doctorate in anthropology as a result it. The teachings of Don Juan Matus included knowledge of plants such as peyote and jimson weed, and their use in inducing supposedly higher states of consciousness. There has been some dispute as to the veracity of Castaneda's claims about his origins and about his meetings with Don Juan. Some have called him a hoax, saying he was not born in Brazil, and point to his reclusiveness as supporting evidence. Others assert that Don Juan was an entirely fictive creation. Castaneda continued his journey with A SEPARATE REALITY and JOURNEY TO IXTLAN, both of which sold well. It is said that Castaneda never allowed himself to be photographed, even when he was featured on the cover of TIME magazine in 1970. However, a book by his former wife includes photos. Castaneda was a member of a "family" of sorcerers, some of whom have written books themselves. Carlos Castaneda died mysteriously, perhaps of a liver ailment, and his death was not known to the world for weeks.
