Do what thou wilt shall be the whole of the Law.
Aleister Crowley was an extremely prolific writer. He wrote volumes upon volumes throughout his lifetime. True to this nature as he was, and always looking for ways to spread the Law of Thelema and further the goals of both himself and the Magickal Orders that he spoke for, he also constantly exchanged in mail correspondence throughout his life. A large number of these letters still exist today. Below, you will find links to as many collections of his letters as we could find on the web. You may also be interested in a book called “The Progradior Correspondence“, by Keith Richmond, that contains a large number of letters between Crowley and his followers, “Brother Curwen, Brother Crowley“, which contains years worth of letters between Crowley and one David Curwen, and “Magick Without Tears” by Aleister Crowley.
