Over 80 years ago a young scholar emigrated from Eastern Europe to Jerusalem. Not long thereafter he received a priceless spiritual teaching that revealed the source of lasting joy & fulfilment from a spiritual master whose name he would never disclose not even after he himself became the most renowned Kabbalist of the 20th century. The young scholars name was Rav Yehuda Ashlag & though his letters & writings offer tantalising hints of the wisdom that was given to him the pieces of the puzzle have never been fully assembled until now. Here Michael Berg himself the descendant of great Kabbalists shares the result of years spent studying Rav Ashlags life & work. In this book Berg shows how the secret offers life-changing power. Drawing on stories & insights from Ashlag & other noted mystics Berg explains how to discover ones true purpose in the world & thereby find lasting peace & joy.
