The Qabalah is one of the great foundations of Western esoteric and spiritual thought. It is an important tool in learning to use the intuition to explore the archetypal realms of divine life.  The Mystical Qabalah is widely recognized as the most practical and authoritative guide to understanding and using the Qabalah. It explains its roots in Jewish mysticism, then demonstrates how this glyph the Tree of Life can be used to understand the emanations of the mind of God.  The author, Dion Fortune, was one of the leading figures in the Western esoteric tradition during the first half of the twentieth century.
