In this introduction to the magnum opus of Isaiah Horowitz--a book-length work in itself--he brought together his views concerning many of the most important issues addressed by kabbalists since the late twelfth century. These include basic theological questions concerning how God can be known, the true nature of the Torah, the divine origins of the human soul, the meaning and purpose of life in this world, the nature of the precepts and the power of the divine intervention with regard to them, and the ultimate reward of the Messianic Age and the World to Come.
