Knights Templar Oasis, in Salem, Massachusetts, is the O.T.O. body serving the Thelemic community in Massachusetts and the surrounding New England states. We teach and practice Thelemic ceremonial magick, celebrate the Gnostic Mass, and are chartered to initiate through the III°. The interests of our membership range widely across esoteric practices and spiritual systems, but all find unity in their acceptance of the principles of The Book of the Law (Liber AL vel Legis). Received by Aleister Crowley in 1904 EV., The Book of the Law proclaims a New Æon in human thought, culture and religion.
