The Zohar is a foundational work of Kabbalistic literature. It consists of a group of books that provide commentary on the mystical aspects of the Torah and various scriptural interpretations.
The text includes material regarding mysticism, mythical cosmogony, and mystical psychology. Its contents explore the nature of God, the origin and structure of the universe, the nature of souls, redemption, and the relationship between the ego to darkness and the "true self" to "the light of God."
