"This is one of the best introductions to Kabbalah I have read. It goes further, and deeper, than many others and it is at the same time balanced, measured andgenerous. This is a book not just for the interested explorer but for those seeking wisdom at the most profound level. This is Kabbalah for the present and thefuture, including the world of science. It is also Kabbalah for daily life, for practice and discovery. I recommend it highly." - John Matthews, author of Arthurian Magic
