Kabbalah's most famous symbol, the Tree of Life, has become the organizing principle behind our human efforts to understand the world. Using Hermann Haindl's lush depiction of the Tree of Life, Rachel Pollack examines the message behind this ancient symbol. She takes a non-denominational approach - drawing upon unusual sources such as tribal and shamanic traditions, modern science, contemporary Kabbalists, tarot interpreters, and a comic book writer - to explore the Tree's meaning. Along the way, we learn more about Kabbalah's history, texts, mystical concepts, and why this esoteric tradition has sprung up again in the twenty-first century.
