Carlos Castaneda (1925-1998) was a Peruvian-born American author. Starting with The Teachings of Don Juan in 1968, Castaneda wrote a series of books that describe his purported training in traditional Mesoamerican shamanism. His 12 books have sold more than 8 million copies in 17 languages.
In his books, Castaneda narrated in first person what he claimed were his experiences under the tutelage of a Yaqui shaman named don Juan Matus whom he met in 1960. Castaneda wrote that he was identified by don Juan Matus as having the energetic configuration of a "nagual", who, if the spirit chose, could become a leader of a party of seers. He also used the term "nagual" to signify that part of perception which is in the realm of the unknown yet still reachable by man, implying that, for his party of seers, don Juan was in some way a connection to that unknown. Castaneda often referred to this unknown realm as nonordinary reality, which indicated that this realm was indeed a reality, but radically different from the ordinary reality experienced by human beings who are well engaged in everyday activities as part of their social conditioning.
