BOOK FOUR, Parts I and II, together with Magick in Theory and Practice (which is Part III of BOOK FOUR) make up a complete course in Magick, with practical instruction in Yoga and mysticism.

Aleister Crowley devoted 25 years to writing and producing the four parts of this book in which he systematically expounds the mystical and magickal theories and techniques taught in his magickal orders the A∴A∴ and O.T.O.

This profusely illustrated new 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 meditiation. 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 the events leading to its reception.

Extensively cross referenced and annotated, this edition features over 100 diagrams and photographs, as well as a glossary, bibliography and detailed index. This second, revised one-volume edition features revisions based on new typescripts for a more accurate text than all earlier editions and it includes a revised A∴A∴ curriculum, a new syllabus of O.T.O. papers and an important, previously unpublished A∴A∴ paper.
