His responsa, as well as his Torah commentaries, published under the title Divrei Chaim, reflect his Torah greatness, his humility, and his compassionate nature. He was a champion of the poor and established many organizations to relieve them of their poverty. He was the first Honorary President of Kolel Chibas Yerushalayim. His compassion and generosity was legendary; he literally gave away everything he had for the needy; and went to sleep penniless. During his 46 years as Rabbi of Sanz; that city was transformed into a vibrant center of Hasidism, attracting tens of thousands of followers. Among his many disciples, are counted such leaders as Rabbi Zvi Hirsh Friedlander of Liska, the Tiferes Shlome of Radomsk, Rabbi Abraham Judah ha-Kohen Schwartz, Rabbi Meir Horowitz of Dzhikov, and the Kedishes Yom Tov of Sighet. He studied with his brother-in-law, Yosef Babad, author of the Minchat Chinuch. References
