The Zohar presents itself as the teaching of Rabbi Shimon bar Yoḥai and his companions in second-century Galilee. Scholars attribute its core to Moses de León in thirteenth-century Castile. In a rich, symbolic Aramaic it interprets the Torah as a revelation of the sefirot and the inner life of God.
