The Book of the Law: Liber Al Vel Legis: With a Facsimile of the Manuscript as Received by Aleister and Rose Edith Crowley on April 8, 9, 10, 1904, Hardcover/Weiser Books

"Do what thou wilt shall be the whole of the Law." This oft-misunderstood phrase, which forms the basis for Crowley's practice of Magick, is found in The Book of the Law. Dictated to Crowley in Cairo between noon and 1 pm on three success days in April 1904, the Book of the Law is the source book and key for Crowley students and for the occult in general.
