The Book of the Law, the holy text that forms the basis of Thelema, was transmitted to Crowley by the entity known as Aiwass in Cairo, on three successive days during April 1904. Acting as a medium, Crowley recorded the communications on hotel notepads and later organized his automatic writing into a short, coherent document. Aiwass/Crowley presents The Book of the Law as an expression of three god-forms in three chapters: Nuit, Hadit, and Ra-Hoor-Khuit.

The Book of Black Magic is Arthur Edward Waite's magnum opus of occult lore; this edition contains the author's original icons, symbols, seals and drawings. This supreme guide to occultist history, lore, magick, and ceremony is split into two parts: The first is entitled ""The Literature of Ceremonial Magic."" Here, Waite examines the ritualistic traditions which surrounding the occult movement for centuries. He notes various texts, and how these had a bearing upon the practice of the occult and of magical ceremony. The second part, ""The Complete Grimoire,"" concerns how those who practice black magic and occult ritual become versed in the craft. The stringent physical and mental requirements, and the need to practice a spiritual attunement and inner ablution, is detailed. Astronomical knowledge of the planets and their movements is a necessity, as is possession of a variety of instruments, plus a deep knowledge of the various symbols and scripts used in occultism.
