The Builders of the Adytum (BOTA, also spelled B.O.T.A., BotA, or B.o.t.A.) is a school of the Western mystery tradition based in Los Angeles which is registered as a non-profit tax-exempt religious organization. It was founded by Paul Foster Case and has its roots in both the Hermetic Order of the Golden Dawn[1] and the Masonic blue lodge system.[2] It was later extended by Ann Davies.[1]
The B.O.T.A. teaches by correspondence, covering esoteric psychology, occult tarot, Hermetic Qabalah, astrology, and meditation techniques. It also holds a variety of ritual services and study groups, some open to the public.[3]
Worldwide membership is around 5,000.[1]
