In this classic book on the Kabbalah, Dr. Sheinkin offers Jews and non-Jews a basic initiation into the origins, history, principles, symbolism, language, and disciplines (including meditation methods) of Jewish spirituality and mysticism. It is an integral treatment of Kabbalah that speaks from the depths of classical Judaism, but is sensitive to contemporary spiritual seekers. The author creates a remarkable synthesis of psychology and mysticism. He gives a vast cosmic view of history within the Kabbalah’s Tree of Life doctrine, resting the outer world in the remarkably profound foundations of the inner world of the ten basic spiritual forces of the sefiroth.
