This is a reference catalog page from the Sacred Texts website, listing primary source documents of Thelema, an early 20th-century occult philosophy founded by Aleister Crowley. The page indexes roughly 100 texts — rituals, instructional manuals, philosophical essays, diaries, and magical workbooks — produced by Crowley and associates within the A∴A∴ and OTO organizations, each entry noting a "Liber" number, an OTO-assigned importance class, and a brief description. The collection spans practical magical instruction (banishing rituals, sex magic, astral projection, Qabalistic study) alongside doctrinal and philosophical works interpreting "The Book of the Law" and the proclaimed new spiritual age, the Aeon of Horus. Distinctively, the catalog reflects Crowley's deliberate synthesis of Western occultism, Eastern religious traditions (Taoism, Buddhism, Hindu yoga), and ceremonial magic into a unified system, with Crowley positioning himself as the authoritative transmitter of a new cosmic dispensation. The page also carries a brief editorial note about OTO copyright claims on texts that may be legally in the public domain — a point of ongoing tension between the organization and the broader community of practitioners and scholars. Someone deciding whether to engage further would find this most useful as a structured entry point into primary Thelemic source material rather than any single sustained argument.
