Rabbi Kalonymus Kalman Shapira was one of the great Hasidic masters of the twentieth century. A brilliant educator, he wrote this work in the 1930's to guide his students in the spiritual path of Hasidism. Discovered after World War II in the ruins of the Warsaw Ghetto, it was quickly accepted as a classic of Jewish spiritual literature.
