Crowley claimed it was dictated to him by a discarnate entity named Aiwass . 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 . </P> <P> 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". </P>
