Waters of Eden 
Waters of Eden: The Mystery of the Mikvah. By Rabbi Aryeh Kaplan. "It has been called the secret of Jewish survival - a mystical connector to the Garden of Eden. What is the mikvah's fundamental connection to birth, marriage, conversion and death?" This is a revealing book that explodes old myths and prejudices and offers insights never before available to the English reading public. The author gathers concepts from the Torah, Talmud, Midrash, Kabbalah, Zohar, and many others. This is the first attempt to explore the ancient Jewish practice of spiritual purification and immersion in contemporary English. Softcover.
