Builders of the Adytum

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 and the Masonic blue lodge system. It was later extended by Ann Davies.

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.

Worldwide membership is around 5,000.
