Carlos Arana Castañeda[1] (December 25, 1925 – April 27, 1998) was a Peruvian-American author with a Ph.D. in anthropology.
Starting with The Teachings of Don Juan in 1968, Castañeda wrote a series of books that describe his alleged training in shamanism. The books, narrated in the first person, relate his supposed experiences under the tutelage of a Yaqui "Man of Knowledge" named Don Juan Matus. His 11 books have sold more than 28 million copies in 17 languages. Critics have suggested that they are works of fiction; supporters claim the books are either true or at least valuable works of philosophy and descriptions of practices which enable an increased awareness.
