A∴A∴

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. 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, practise, and teach "scientific illuminism".

The A∴A∴ claims to have been present in all societies and epochs, although not necessarily under that name.

The A∴A∴ in its modern form was formulated in 1907 by Aleister Crowley and George Cecil Jones, claiming authority from Aiwass (the Author of The Book of the Law) and other Secret Chiefs of the planetary spiritual order after the schism in and subsequent collapse of the Hermetic Order of the Golden Dawn at the turn of the Twentieth century. The principal holy book of the A∴A∴ is the book Crowley called "AL" and "Liber Legis", technically called "Liber AL vel Legis sub figura CCXX as delivered by 93=418 to DCLXVI", whose scriptural title is The Book of the Law, by which name the Book is most commonly known and referred to. There are several other holy books venerated in A∴A∴, which comprise the so-called Class A and AB material.

In 1909 the O.T.O. considered itself to be a "close ally" of the A∴A∴, both organisations having accepted the authority of the Book of the Law, although the O.T.O., being a temporal and fraternal society, in no way participates in the A∴A∴'s strictly hierarchic and spiritual initiatory program, nor does O.T.O. represent A∴A∴. or transmit its functions or authority.
