This is a catalog/index page from the Sacred Texts website listing Thelemic texts, primarily works by Aleister Crowley and associated authors within the A∴A∴ and OTO (Ordo Templi Orientis) occult organizations. The page serves as a reference directory rather than a single cohesive argument, organizing dozens of ritual, philosophical, and instructional texts under their traditional "Liber" numbering system along with OTO classification grades. The texts listed span practical magical instruction (rituals, invocations, yoga techniques), philosophical and ethical treatises, sexual magic, initiatory documents, and Crowley's translations of Eastern classics like the Tao Teh Ching and Khing Kang King. A distinctive feature is the editorial note addressing copyright tensions: the OTO claims intellectual property rights over many documents that are technically public domain, and the site takes a stance of preserving them for non-commercial use. The catalog reveals the eclectic synthesis at Thelema's core — drawing on Qabalah, Egyptian mythology, Tantra, Buddhism, Taoism, and Enochian magic — making it a useful orientation map for someone researching Western esotericism or Crowley's output, though the page itself contains no sustained argument or analysis.
