The Zohar is, undoubtedly, the most famous work of the mystical universal thought, and particularly of the Kabbalah . Rabbi Simn Bar Iojai and his pupils, out of space and out of time, analyze, investigate and scrutinize the deepest and hermetic topics of human existence. This volume deals mainly with the deeper meaning of the fight between Jacob and the Angel, the change of Jacobs name to Israel, the dreams of Joseph and the sale of Joseph by his brothers. This work also includes a study about the mystery of the twelve tribes of Israel.
