Christophe Bourceier is a well-known author in France, who has published more than twenty books since 1989, as well as a film actor who has starred in a number of films, including Jean-Luc Godard. The book “Carlos Castaneda. The Truth of Lies" is the first full-fledged biography of Carlos Castaneda, who can safely be ranked among the greatest mysteries of the 20th century. Castaneda's books were published in millions of copies and were translated into 17 languages, including Russian. All that is known for certain about him is that he is the author of ten best-selling books and the founder of the company that now owns the rights to his creative heritage. Everything else is nothing more than assumptions, if not speculation. Castaneda carefully kept his identity secret, practically did not give interviews and categorically refused to be photographed. And only now, with the appearance of Christophe Bourceier’s book, can we talk about the existence of a real biography that reveals many of the secrets of Carlos Castaneda, most of which he himself created. Why did he do this? What is the secret of the attractiveness of his personality? These questions are answered by Christophe Bourceier, who became interested in Castaneda’s work as a child.
