The Holy Books of Thelema

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

The Holy Books of Thelema are the foundational text of the spiritual system of Thelema. Received by Aleister Crowley first in April of 1904 e.v. was Liber AL vel Legis with the others to be received between 1907-1911 e.v. with the first handful published in the 3 volume Θελημα, published for aspirants of A.˙.A.˙. and then published in a single volume in 1983 under the guidance of Frater Hymenaeus Alpha. 

The Holy Books of Thelema are class A texts. Class A means: Class “A” consists of books of which may be changed not so much as the style of a letter: that is, they represent the utterance of an Adept entirely beyond the criticism of even the Visible Head of the Organization.
