The A∴A∴ is a spiritual organisation described in 1907 by occultist Aleister Crowley. Its members are dedicated to the advancement of humanity by perfection of the individual on every plane through a graded series of universal initiations. The A∴A∴ claims to have been present in all societies and epochs, although not necessarily under that name. Its initiations are syncretic, unifying the essence of Theravada Buddhism with Vedantic yoga and ceremonial magic. The A∴A∴ applies what it describes as mystical and magical methods of spiritual attainment under the structure of the Qabalistic Tree of Life, and aims to research, practice, and teach "scientific illuminism".
The organisation's motto is "The method of science, the aim of religion."
