The Book of the Law

Blurb

Liber AL vel Legis is the central sacred text of Thelema, written down from dictation mostly by Aleister Crowley, although Rose Edith Crowley is also known to have written two phrases into the manuscript of the Book after its dictation. Crowley claimed it was dictated to him by a discarnate entity named Aiwass or Aiwaz. However, the three chapters are largely written in the first person by the Thelemic deities Nuit, Hadit, and Ra-Hoor-Khuit respectively, rather than by Aiwass/Aiwaz.
Through the reception of the Book, Crowley proclaimed the arrival of a new stage in the spiritual evolution of humanity, to be known as the "Æon of Horus". The primary precept of this new aeon is the charge to "Do what thou wilt".
The book contains three chapters, each of which was alleged to be written down in one hour, beginning at noon, on 8 April 9 April, and 10 April in Cairo, Egypt, in the year 1904. Crowley says that the author was an entity named Aiwass, whom he later referred to as his personal Holy Guardian Angel.
