Distilling the teachings and thought of Rabbi Simha Bunim, one of the foremost figures in the Przysucha school of Hasidism, this study sheds light both on what students of the Pryzsucha tradition believed as well as on its influence on Polish Hasidism at large. Pryzsucha Hasidism believed in a service to God that demanded both passion and analytical study, and sought to understand the human being, rather than God himself. This exploration of Rabbi Bunim's thought illustrates how the spiritual leader was able to transform Przysucha Hasidism into a genuine movement and, in doing so, become the dominant personality in the Hasidic community in Poland during the early part of the 19th century.
