Sword and Serpent Oasis, O.T.O.
Ordo Templi Orientis 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.
The Law of Thelema
The Book of the Law lays down a simple Code of Conduct.
“Do what thou wilt shall be the whole of the Law.”
“Love is the law, love under will.”
“There is no law beyond Do what thou wilt.”
This means that each of us stars is to move on our true orbit, as marked out by the nature of our position, the law of our growth, the impulse of our past experiences. All events are equally lawful— and every one necessary, in the long run— for all of us, in theory; but in practice, only one act is lawful for each one of us at any given moment. Therefore Duty consists in determining to experience the right event from one moment of consciousness to another.
Each action or motion is an act of love, the uniting with one or another part of “Nuit”; each such act must be “under will,” chosen so as to fulfil and not to thwart the true nature of the being concerned.
