Rabbi Israel ben Eliezer, the Baal Shem Tov ("Master of the Good Name"), founder of Hasidic Judaism. He taught that joy, not asceticism, was the path to God, and that the simple Jew who prays with a full heart outweighs the distracted scholar. He told stories. He healed. He worked in the forests and mountains before anyone knew who he was.
On their voice
Eastern European Jewish world, 18th c. CE. A time of poverty, anti-Jewish violence, and the aftermath of the Sabbatean catastrophe. The Besht built a movement around accessible joy and the presence of God in all things. His teachings were transmitted orally through disciples; most of what we have is report, story, parable.
