About the Author
Aleister Crowley (1875-1947), also known as 'The Great Beast' and the 'Wickedest Man in the World,' was one of the most profound students of Magick, Qabalah and yoga psychology. His vast influence reaches through all modern occultism. He is widely recognized as the first Western investigator to give initiation a truly scientific method. In reconciling occultism to physical science, mathematics and philosophy, Crowley achieved a lasting synthesis that remains unsurpassed for depth of insight and comprehensiveness.
