Peter 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.
