Ner Mitzvah V'Torah Or
Ner Mitzvah V'Torah Or is a work of Chassidus authored by the Mitteler Rebbe, Rabbi Dovber Schneuri of Lubavitch. This sefer was first published in Kopust in 1820, during the lifetime of the Mitteler Rebbe.
The sefer is structured as two parts or "gates" (she'arim). The first part is entitled Shaar HaEmunah (The Gate of Faith), and discusses the topics of the Yetziyas Mitzrayim (the Exodus from Egypt), the eating of Matzah and the Splitting of the Sea. The second part, named Shaar HaYichud, contains a concise explanation of the Seder Hishtalshelus.
