The Book of the Law
"The Book of the Law, or Liber AL vel Legis as it is also called, is the primary text of the Ordo Templi Orientis, which was dictated to Aleister Crowley by his Holy Guardian Angel, Aiwass in 1904 while he was travelling in Egypt.
This book discusses the way of the Universe, of life and of existence, and describes the basic rights of every man and woman. It also speaks about what to expect from the new aeon, dubbed the Aeon of the Child, which is the current time period in which people enter a period of self-realization and develop a growing interest in the spiritual. The text itself is composed in an exceptionally dynamic manner which begs self-examination and pondering from the reader.
The central philosophy of the Book of the Law is that every man and woman has their own unique divine purpose or True Will that operates in perfect harmony with the universe itself."
