Arthur Green blends meticulous historical scholarship with delicate textual analysis and poetic writing to help us understand anew the life and teachings of one of the most important leaders of early Hasidism, a daring theologian who was also remembered as a popular spiritual hero and an iconic Jewish leader. Much like his pathbreaking intellectual and religious biography of Rabbi Nahman of Bratslav, Green inspires us again. This book is a must read for scholars and seekers alike!
