Aleister Crowley wrote the Gnostic Mass in 1913. He described it as the central ritual, public and private, of Ordo Templi Orientis (O.T.O.). It is a mythic hymn to the wedding of scientific truth and religious aspiration; the celebrant is encouraged to leave superstition and dogma at the door and join in an ecstatic tribute to the glorious nature of reality. The Gnostic Mass offers a truly modern spirituality and it is being performed on a regular basis throughout the civilized world.
