Magick: Liber ABA Book 4

Blurb

Magick, Liber ABA, Book 4 is widely considered to be the magnum opus of 20th-century occultist Aleister Crowley, the founder of Thelema. It is a lengthy treatise on Magick, his system of Western occult practice, synthesised from many sources, including Eastern Yoga, Hermeticism, medieval grimoires, contemporary magical theories from writers like Eliphas Levi and Helena Blavatsky, and his own original contributions. It consists of four parts: Mysticism, Magick, Magick in Theory and Practice, and ΘΕΛΗΜΑ—the Law. It also includes numerous appendices presenting many rituals and explicatory papers.
In November 1911, Crowley carried out a ritual during which he reports being commanded to write Book 4 by a discarnate entity named "Abuldiz" in Crowley's incomplete record of the working, which came around the time that Liber Legis was ready to be published in The Equinox Vol VII. The working was published in The Equinox Vol. VIII of Vol I. The writing of Book 4 was duly accomplished with the aid of his seer Soror Virakam at a villa in Posillipo near Naples, Italy, and was published in the winter of 1912–1913 in The Equinox Vol. VIII of Vol I.
