Theosophy, Western Approach to Eastern Mysticism

Theosophy gives an outline of universal principles, the operations of which can be recognized by everybody with an open mind.

Recognition of these principles is possible through gradual development of the faculty of understanding (by unselfish service to mankind combined with esoteric study).

All these principles can be found in the literature of many religions, especially the mystical sections, e.g. Sufism, Gnosis, ancient Kabbalah, certain parts of Buddhism, Hinduism, etc, as well in old myths.
