The Book of Deuteronomy is the final book of the Five Books of Moses, said to have been written by Moses himself. Moses waited 40 years for permission by the Creator to admonish the Israelites for their mistakes, interpreted by kabbalists as teaching the Israelites the Universal Law of Cause and Effect. With this teaching, Moses helped to spiritually prepare their souls for entering the land of Israel. According to Kabbalistic tradition, the day an elevated soul like Moses leaves this world, he reveals secrets that he was previously unable to reveal. The Book of Deuteronomy is this revelation. Deuteronomy is edited and features contemporary insights by noted Kabbalah scholar and teacher Yehuda Berg. The text is complimented by excerpts from the Zohar and from the writings of three of history's greatest Kabbalists, Rav Yehuda Ashlag, Rav Yehuda Brandwein, and Rav P.S. Berg.
