The Kabbalah, the Jewish mystical tradition, extends from the ist cent, to the present. The printed literature comprises about 3,000 texts, and many more have never been printed. The two most important texts are the Sefer Yetsirah (Book of Creation) … and the Sefer Ha-Zohar (Book of Splendour), 13th cent.
Jung provides a concise authoritative definition of the Kabbalah’s scope and canonical texts, signaling his serious scholarly engagement with the tradition rather than mere occult appropriation.
