The Book of Lies (full title: Which is also Falsely Called BREAKS. The Wanderings or Falsifications of the One Thought of Frater Perdurabo, which Thought is itself Untrue. Liber CCCXXXIII) was written by English occultist and teacher Aleister Crowley (using the pen name of Frater Perdurabo) and first published in 1912. As Crowley describes it: 'This book deals with many matters on all planes of the very highest importance. It is an official publication for Babes of the Abyss, but is recommended even to beginners as highly suggestive.'
