This is a ceremonial magic ritual text by Aleister Crowley, known as *Liber Samekh* (composed at the Abbey of Thelema in Cefalù, 1921), which is his Thelemic redaction of the ancient Greek Magical Papyri's "Bornless" or "Headless Ritual." Its stated purpose is achieving "Knowledge and Conversation of the Holy Guardian Angel" — the central initiatory goal in Crowley's Thelemic system, adapted from the grimoire tradition of the Sacred Magic of Abramelin the Mage. The ritual is structured in elemental sections (Air, Fire, Water, Earth, Spirit), each built around sequences of "barbarous names" drawn from the Greek papyri, to which Crowley appends his own Qabalistic and etymological glosses — translating cryptic voces magicae into Thelemic theological statements about Nuit, Hadit, Satan-as-solar-force, and Babalon. The commentary that follows the invocation text is notably distinctive: Crowley reframes the ritual's climax in explicitly psychoanalytic terms, equating the HGA with the Jungian unconscious and the magical "orgasm" with a psychological death-of-ego, while also drawing on Yoga and Qabalistic number-symbolism to explain each line. The work is primarily of interest to scholars of Western esotericism, Thelema, or the history of the Greek Magical Papyri's reception, and to practitioners within the Thelemic or broader chaos-magic traditions for whom it remains a living liturgical text.
