A Study of the Ten Luminous Emanations, Volume 1: The Wisdom of the Kabbalah by Rabbi Yehuda Ashlag Z"l as Revealed by the Writings of Rabbi Isaac Lur

Before our universe came into existence there existed an infinite endless realm of total fulfillment and perfection. Suddenly it all seemed to vanish and the Big Bang was born leaving behind a finite realm of existence where chaos suffering and pain would apparently be the rule. The most profound mystic of the 20th century Rabbi Yehuda Ashlag reveals the process of creation leading up to the Big Bang origins of our universe.
