The OTO is the first of the Old Aeon orders to accept The Book of the Law, received by Aleister Crowley in 1904 e.v., with its message of a revolution in human thought, culture, and religion based on a single supreme injunction:

Do what thou wilt shall be the whole of the Law.

This is not to be interpreted as a license to indulge every passing whim, but rather as the mandate to discover one's True Will and accomplish it, leaving others to do the same in their own unique ways.

The structure of OTO, like that of Freemasonry and the ancient mystery schools, is based on a series of initiations, or degrees. In these degrees, the OTO seeks to instruct the individual through allegory and symbol in the profound mysteries of existence, and thereby to assist each to discover his or her own true nature. Every man and woman of full age, free, and of good report, has an indefeasible right to the introductory degrees of the OTO. For more information on initiation, contact our Initiation Secretary.

"What does "Aum. Ha." mean? [Aum. Ha.] consists of the two Sanskrit words, aum ha, the first and last letters of the (devanagari) Sanskrit alphabet--thus equivalent to the Greek "Alpha and Omega," the beginning and end and, implicitly, the eternity that passes between. The first, aum, most often written in English as om, is a sacred syllable representing the course of breath and the life-cycle--creation, preservation, destruction--"a symbol both of the Personal God and of the Absolute" (Swami Vivekananda). It is "at once an invocation, a benediction, an affirmation, and a promise" (G.A. Barborka). Ha is an expulsion of breath and a word for the Sun. As a pun, it is also the Hebrew word for "behold," etc. One translation of the phrase aum ha, therefore, might be "Alpha & Omega, The Sempiternal Sun."" (by James Eshelman)
