Welcome to Therion-Babalon Oasis, OTO!

Ordo Templi Orientis is a guru-free society of women and men dedicated to the path of spiritual self-realization and the establishment of Universal Brotherhood. Located in Berkeley, California, Therion-Babalon Oasis is a chartered local body of U.S. Grand Lodge O.T.O. Our core activities include the weekly celebration of The Gnostic Mass, the administration of our ceremonies of initiation, and the development of an energetic community founded upon the principles of Thelema.

Guests are welcome at our many public events, especially the Gnostic Mass. To find out if you might be interested in attending one of our events, or if you are merely curious about O.T.O. and Thelema, you are invited to explore the various sections below and to email us with any questions you might have.
