Discourses delivered by the Tzemach Tzedek, Rabbi Menachem M. Schneersohn of Lubavitch. While the bulk of the voluminous Chasidic teachings of the third leader of Chabad were penned by the Rebbe himself, these discourses were delivered orally and transcribed by the listeners. Many of them were recorded by Rebbe’s son and successor, Rabbi Shmuel.
