The book of Zohar (Radiance), also known as The Zohar, contains all the secrets of creation. The great Kabbalist, Yehuda Ashlag (1884-1954), authored The Sulam (Ladder) commentary on The Zohar, making it accessible to all. Let There Be Light contains selected excerpts from the series Zohar for All, a refined edition of The Sulam commentary. Each piece was carefully chosen for its beauty, depth, and capacity to give the reader the most rewarding reading experience.
