"Kabbalah," according to Orthodox rabbi, lawyer, and educational psychologist Laibl Wolf, "is practical, and its knowledge is universal. The insights provide a model that is as comfortable in Western psychology and Eastern mysticism as it is in Jewish spiritual practice." These mystical teachings arose in the medieval period of history as "tools to tame the ego mind and harness haphazard emotions." Rabbi Wolf explores mind as the way the soul expresses itself through the physiology of the brain. Then he dissects emotion as the way the soul is manifested through the metaphoric heart.

Using meditations and visualization exercises, the author assesses the ten spiritual flows known as the Sefirot. Rabbi Wolf notes that from Hasidic teachings we learn that the purpose of the descent of any soul may be simply to do one loving deed for another person. When the soul has accomplished this mission, its reason for being may have been totally fulfilled. Doing a mitzvah (a good deed) is part and parcel of contributing what we can to the unfinished act of creation. Rabbi Wolf reveals the relevance of Kabbalistic teachings to the soul's journey in the world.
