Addressing various aspects of Jewish life and religion, particularly in the last two centuries, this book examines different aspects of the Hasidic tradition; present-day contacts between Bobower Hasidism in New York and Bobowa in Poland; and how a rabbi trained in the Lithuanian tradition adapted to the very different conditions of the United States. The modifications of Jewish religious tradition practiced in the modern pre-war synagogues in Warsaw, L dz, and Lw w are considered, as is the attempt by Hillel Zeitlyn to re-interpret Jewish tradition in the interwar years.
