Invaluable book. It's not 777, not close. It's a very practical manual, easy to read, easy to apply. Well, that may be subjective, but it's concise and well written in any case, and very clearly expressed.
Another book, Kabbalistic Life Cycles and the Mastery of Life, is proving to be an incredible book as well, not just for magical practice, but really for all aspects of life. Practical Kabbalah in a very comprehensible mode.
Kabbalistic Handbook is about understanding and applying the kabbalistic analysis of ritual work, it's immediately applicable for basic ritual work, evocation, even daily meditation. Definitely get it if you have any interest in the kabbalistic tradition in relationship to magic which, everyone should. (IMG:
