Sefer Yetzirah has been called the foundational text of Jewish mysticism, but despite many scholarly attempts to explain it, readers still find its language baffling and its message indecipherable. Now Rabbi Jill Hammer has clarified the text for us all. Without ruining its mystery, she reveals its cosmic vision of “space, time, and body-soul.” Beyond this, she has created a new-ancient meditative practice based on this mystical masterpiece. Her superb achievement is a gift for all of us!
