Jewish mystics from biblical times to the present have explored the hidden secrets of the Torah in quest of a single goal: to lose the self in the Infinite "No-thingness" (Ein Sof) and be at one with God. In language accessible to the layperson, this Shambhala Guide provides a detailed introduction to the complex world of Kabbalah and Jewish mysticism. With an extensive background in meditation practice, Perle Besserman emphasizes Kabbalah's spiritual disciplines, grounded in righteous living, devotional practices, and meditation. She discusses the Kabbalistic universe, including the four worlds and ten sefirot; Jewish meditation techniques and instructions for beginning meditation; mystics and teachers from Rabbi Akiva and the Baal Shem Tov to Aryeh Kaplan; the often uneasy relationship between Kabbalah and mainstream Judaism; and incorporating the ancient wisdom of Jewish mysticism to life in the world of today.
