I ordered the series of workbooks exploring the teachings of the Qabalah (Kabbalah) and Tree of Life. The books were easy to read, study and understand. It was a very enjoyable experience. The books are just the tool especially for busy people who want to read about the subject but have limited time. They give you a good grasp of the teachings and help you to work on your own transformation. They are a work of art and deserve a place in main book shops.
