A classic by the author of Keys to the Kingdom, this book was the first to present traditional Kabbalah from a scientific orientation-showing how it clearly relates to Quantum Theory, Relativity and the Big Bang. This guide to Kabbalah also explores Kabbalist principles, in addition to important rites, ritual, and magic. Also included are tables of the Hebrew alphabet, Divine names, planetary hours, correspondences related to the Tree of Life, and more!
