O.T.O. Rituals and Sex Magick by Aleister Crowley and Theodor Russ.
 
This volume collects the foundational rites, teachings, and esoteric sexual practices of the Ordo Templi Orientis (O.T.O.), as shaped by Theodor Reuss and significantly expanded by Aleister Crowley.
 
Originally conceived by Reuss as a quasi-Masonic order, the O.T.O. evolved under Crowley’s leadership into a distinctly Thelemic initiatory system, centered on the spiritual and magical potential of sexual energy.
 
The rituals contained here range from the early degree ceremonies—structured with initiatory symbolism and Hermetic allegory—to the highly secretive IX° teachings, which outline specific techniques of sex magick. These are not merely symbolic rituals, but practical operations meant to harness and transmute erotic force into spiritual awakening. Crowley’s influence permeates the work with references to Liber AL vel Legis and the Law of Thelema, emphasizing will, ecstasy, and union with the divine.
