According to Jewish mysticism, the souls of a husband and wife originate in the same undifferentiated spiritual essence. These souls are bound as one, and the purpose of marriage is to enable a couple to manifest this unity in the context of everyday life. Rabbi Yitzchak Ginsburgh shows how the natural process of mating of establishing a healthy relationship, fostering togetherness, and ultimately merging into true oneness--is a spiritual act of the highest order. Drawing on modern psychology and Kabbalistic wisdom, with many illustrations from Biblical personalities, the author traces the steps through which today's married couple can actualize their relationship ideals in their daily life. Includes glossary, footnotes, and index.
