Kabbalah, the mystical element of Judaism, has undergone an unprecedented surge in popularity in recent years. In Endless Light David Aaron, a rabbi who lives in Jerusalem, presents the ancient system as a source of personal and spiritual sustenance. In the kabbalah, the creation of the universe is an ongoing process; thus, Aaron says, we derive happiness from the journey to our goals rather than from reaching our destination. "If you are ready to see [life] as the challenge of any good game--where the challenge itself is what makes it fun--then your life will not be static, but a dynamic process of growth," he writes. The philosophy he presents is derived from the Torah and other Jewish texts and traditions, but Aaron makes it comprehensible to anyone seeking a new understanding of God, the world, and themselves.
