According to Wikipedia, Crowly was,
…an English occultist, ceremonial magician, poet, painter, novelist, and mountaineer. He founded the religion of Thelema, identifying himself as the prophet entrusted with guiding humanity into the Æon of Horus in the early 20th century. A prolific writer, he published widely over the course of his life.
In the Wiki article specifically about The Book of Lies, the author says,
“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.”
The book consists of 91 chapters, each of which consists of one page of text. The chapters include a question mark, poems, rituals, instructions, and obscure allusions and cryptograms. The subject of each chapter is generally determined by its number and its corresponding Qabalistic meaning
Well, that clear up everything.
