These Mysteries are a set of congregational rituals commemorating the attainments of Aleister Crowley, the Prophet of Thelema. Although originally developed for and with the cooperation of local O.T.O. groups, they are suitable for performance by any Thelemites. They can be conducted on the "unholy days" to reflect their historical inspiration, or in a day-long festival which arranges them into a single larger event.
