Kabbalah
Kabbalah is a set of esoteric teachings meant to explain the relationship between the unchanging, eternal God—the mysterious Ein Sof ( אֵין סוֹף, “The Infinite”)—and the mortal, finite universe (God’s creation). It forms the foundation of mystical religious interpretations within Judaism.

Jewish Meditation: A Practical Guide
Kaplan shows that meditation is consistent with traditional Jewish thought and practice. The book presents a variety of meditative techniques to help make the reader a better person, and develop a closer relationship to God. (This is my best book!)
