Its said that the greatest trick the Devil ever pulled was in convincing the world that he doesnt exist. In his latest book, Yehuda Berg uses the device of an ''as told to'' autobiography to explain the notion of The Adversary, an important concept in Kabbalistic wisdom. Through this playful yet serious faux-bio, readers learn that Satan resides within everyone, manifesting himself as that nagging little voice of doubt and uncertainty, and that that's how havoc is wreaked throughout the world. By doing the spiritual work that Kabbalah teaches, readers can banish negativity and evil influences from their lives, and eliminate chaos from the world. Berg takes creative license with the narrative, but he presents an accurate representation of Kabbalahs view on the force of evil in the physical universe.
