The third Chabad Rebbe, Rabbi Menachem Mendel Schneersohn, the "Tzemach Tzedek" (1789-1866), authored many important works on Halacha and on Chasidic thought. His Chasidic teachings are published in his multi-volume series Ohr Hatorah, which is a vast compendium of Chasidic thought.
Discourses delivered by the Tzemach Tzedek, Rabbi Menachem M. Schneersohn of LubavitchWhile 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.
