The founder of Chassidism, the Besht single handedly reinvigorated mystical Judaism in a demoralizing period. He emphasized the power of each individual soul; the concepts of love of your fellow; serving G-d with joy; Divine Providence and perpetual creation. The Besht’s great student, Rabbi Dovber, the Maggid of Mezritch, continued his legacy and passed it on to his many students, who became the founders of each of their respective Chassidic dynasties.

Published Writings:
The Baal Shem Tov, like the Arizal, did not write his teachings. They were recorded by his students and passed on from generation to generation through Rebbes and Chassidim. Much of what we know is from the writings of the Baal Shem Tov's foremost disciple, Rabbi Yakov Yosef of Polonoye, the author of the first Chassidic work ever published, Toldos Yakov Yosef. He also published Ben Poras Yosef, Tzafnas Paneach, and Kesones Pasim. Other major sources for the teachings of the Baal Shem Tov are Kesser Shem Tov, Tzava’as Harivash, Magid Devarav L'Yakov (written by the Mezericher Maggid, the Baal Shem Tov's successor), Degel Machaneh Ephraim, and Ohr HaMei'ir.
