The letters O.T.O. stand for Ordo Templi Orientis, the Order of Oriental Templars, or Order of the Temple of the East. O.T.O. is an Outer Thelemic Order which is dedicated to the high purpose of securing the Liberty of the Individual and his or her advancement in Light, Wisdom, Understanding, Knowledge, and Power through Beauty, Courage, and Wit, on the Foundation of Universal Brotherhood.
The structure of the O.T.O., like that of Freemasonry and the ancient mystery schools, is based upon a graded series of initiations or Degrees. In these Degrees, O.T.O. seeks to instruct the individual by allegory and symbol in the profound mysteries of Existence, and thereby to assist each to discover his or her own true Nature.
O.T.O. is the first of the great Old Æon orders to accept The Book of the Law, received by Aleister Crowley in 1904 EV. This book proclaims a New Æon in human thought, culture and religion. The Æon arises from a single supreme injunction: the Law of Thelema, which is "Do what thou wilt". This Law 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. "Every man and every woman is a star."
The Law of Thelema can ultimately be fulfilled only through the individual efforts of each person. Nevertheless, many worthy aspirants to the Great Work of Thelema have a genuine need for information, guidance, fellowship, or the opportunity to assist their fellow aspirants and serve humanity. Such aspirants will find welcome in the O.T.O.
