complete idiot's guide to Jewish spirituality and mysticism

The book is an introduction to the origin of the spiritual side of Judaism. It is divided into five sections dealing with the Bible (first 2 sections); the spiritual and mystical ways that Jews and God communicate with each other; mystical texts such as the Kabbalah the Zohar as well as other aspects of mystical Judaism; and finally some of the intriguing aspects of Judaism such as Gematria (replacing Hebrew letters with numbers).
