A Jewish cabalistic book attributed by tradition to Rabbi Simon ben Yochi, who lived about the end of the 1st century, a. d. Modern critics believe it to be a compilation of the 13th century.

Hebrew, "brightness," a mystical commentary on the Pentateuch written from the second to the thirteenth century and a principal source of the cabala.

"Book of Splendor"; the chief literary work of the kabalists. The author of the main part of the Zohar was Moses de Leon (12th century) in Spain, but it is pseudepigraphically ascribed to the Palestinian tanna Simeon bar Yohai (2nd century CE), sometimes called RaShBaY (Rabbi Shimeon bar Yohai).

The Zohar (Hebrew זהר "Splendor, radiance") is widely considered the most important work of Kabbalah, Jewish mysticism. It is a mystical commentary on the Torah (the five books of Moses), written in medieval Aramaic and medieval Hebrew. It contains a mystical discussion of the nature of God, the origin and structure of the universe, the nature of souls, sin, redemption, good and evil, and related topics.
