People like Rose Edith Crowley

Liber AL vel Legis (Classical Latin: [ˈlɪbɛr aː.ɛɫ wɛl‿ˈleːgɪs]), commonly known as The Book of the Law, is the central sacred text of Thelema. Aleister Crowley said that it was dictated to him by a beyond-human being who called himself 'Aiwass'. Rose Edith Kelly, Crowley's wife, wrote two phrases in the manuscript. The three chapters of the book are spoken by the deities Nuit, Hadit, and Ra-Hoor-Khuit.

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, "Do what thou wilt shall be the whole of the Law."

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. Biographer Lawrence Sutin quotes private diaries that fit this story and writes that "if ever Crowley uttered the truth of his relation to the Book," his public account accurately describes what he remembered on this point.
