"The most original and probably the most important writer on Magick since Aleister Crowley."-Robert Anton Wilson, author of the Prometheus Rising and other worksPeter Carroll's classic work has been profound influence on the Western magical world and on the practice of chaos magick in particular. In Liber Null and Psychonaut, Carroll presents an approach to the practice of magic that draws on the foundations of shamanism and animism, as well as that found in the Greek magical papyri, the occult works of Eliphas Levi and Aleister Crowley, and the esoteric meditative practices of classical India and China. Also very much at work in the text are 20th century scientific ideas of quantum physics and chaos theory.The result is a profoundly original work of magical studies that also includes a selection of extremely powerful rituals and exercises for committed occultists with instructions that lead the reader through new concepts and practices to achieve Carroll's definition of magic itself: the raising of the whole individual in perfect balance to the power of infinity.This Weiser Classics edition is a thoroughly revised republication of Liber Null and Psychonaut, first published by Weiser in 1987, and includes a new foreword by Ronald Hutton, a leading authority on modern witchcraft and paganism.
