This book is the final book of the Five Books of Moses, said to be written by Moses himself. Before he dies, he recounts the story of the Israelites' exodus from Egypt until the time they were about to enter the land of Israel. Moses waited forty years before being given permission by the Creator to admonish the Israelites and make them aware of their mistakes. This was nothing more than 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 the wisdom of Kabbalah, 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.
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 Berg.
