This book is very different from traditional Kabbalah books, as it not only provides a systematic analysis of the primary source Sefer Yetsir (Book of Creation), but also of the concepts and various schemes of the Tree of Life (Sephiroth Tree). A study of the Hebrew alphabet and revealed its hidden structure, which allowed us to look differently at the arrangement of the letters in the Tree of Sefirot. It shows the difference between different schemes of the Sephiroth Tree, and slightly uncovers their mystery. The book is not only for Kabbalah scholars, but it is intended for practicing Kabbalists as well as for beginners who are interested in Kabbalah.
