Aleister Crowley

Book 4, Pt. 2 - Magick (Theory) (1929)

Thelema,  Crowley

Magick is Part 2 of Aleister Crowley's four-part masterwork Magick: Liber ABA, Book Four, a foundational resource of modern magick, occultism, and hermeticism. Crowley's unparalleled knowledge of magick (which is defined as the effort, in Wicca and certain other belief systems, undertaken to affect personal transformation or external change), acquired as both scholar and practitioner, made him one of the world's leading experts on the subject. He was a British occult mystic who even created his own esoteric, magick-based spiritual philosophy called Thelema, for which he wrote the sacred texts.
