This book grew, in part, out of an undergraduate course Dr. Levy taught at the San Francisco Art Institute. Finding that students were still subscribing to the 19th-century bohemian myth that to have a vision, one had to, in the words of Rimbaud, "systematically derange" one's senses, he attempted to expose them to an alternative myth that is more positive -- a myth rooted in the grounded practice of shamanic techniques.
