This is a catalog/index page from the Sacred Texts website listing the Thelema collection — a large corpus of esoteric and occult texts, most authored by Aleister Crowley, the early 20th-century British occultist who founded the magical order A.'.A.'. (Argentium Astrum). The page organizes roughly 100+ works by their traditional "Liber" numbering system, noting each text's OTO classification (A through E, indicating relative importance), and providing brief descriptions of content ranging from ritual instruction to philosophical commentary. The collection spans practical magical training manuals (covering Qabalah, astral projection, yoga, and sexual magick), initiation rituals for various grades within the A.'.A.. hierarchy, poetic and allegorical works, and doctrinal texts elaborating Crowley's central law "Do what thou wilt." Notable inclusions are Crowley's translations and commentaries on Eastern texts (the Tao Teh Ching, Blavatsky's Voice of the Silence), writings by associated figures like Jack Parsons and Frater Achad, and texts dealing with sexual magick that are described as "veiled in symbolism." The page is primarily bibliographic rather than argumentative, serving as a navigational index for researchers or practitioners seeking primary Thelemic source material, with a brief note that the OTO claims copyright on some documents despite their public domain status.
