Jerusalem and Sao Paulo is a pioneering work of over four years of anthropological research on the "repentance", or return to Jewish roots phenomenon, in the city of Sao Paulo, Brazil. The return-to-Jewish-roots phenomenon is identified by its Hebrew name of teshuvah, and the individuals involved are called "baalei teshuvah" (repentants). Jerusalem and Sao Paulo describes the long process these young people undergo in their choice of Jewish Orthodoxy. Due to the fact that Judaism is an ortho-practical religion, which emphasizes praxis over belief and dogma, the conversion to Orthodoxy is radical, traumatic, and more encompassing than that experienced by other Brazilians who adopt religions such as Neo-Pentacolism, Buddhism, Taoism, and Afro-Brazilian creeds. The book examines the following processes and contexts and their interrelationships: Globalization of religion, the Brazilian market of religious goods, the History of the Jewish community in Sao Paulo, and the teshuvah movement in Israel and the United States.
