This profusely illustrated edition brings together the complete texts of all four parts of Liber ABA (Book 4) in one volume under the overall title Magick. This edition incorporates Crowley`s own additions, corrections, and annotations, and restores dozens of passages omitted from the first editions.

Magick is the fundamental textbook of modern magick in the New Aeon. It also has invaluable teachings for students of Yoga and meditation. Crowley mastered the practices of Yoga during his studies in the East, and writes about them lucidly, without recourse to the imprecise language of mysticism.

Beginning with a discussion of the universal origin of world religions in mystical revelation, Magick then explores the theory and practice of mysticism and magick in the light of modern scientific thought. Crowley`s own revelation, The Book of the Law, is then treated as a case study, with an autobiographical study of events leading to its reception.
