THE PATH OF THE JUST - Mesillas Yesharim
given by Rabbi Dovid Horowitz
Mesillat Yesharim or Mesillas Yeshorim (Hebrew: מסילת ישרים, lit. "Path of the Just") is an ethical (mussar) text composed by the influential Rabbi Moshe Chaim Luzzatto (1707–1746). It is very different from Rabbi's Luzzato other writings, which are more philosophical.
Mesillas Yesharim is probably Luzzato's most influential work, widely learned in virtually every yeshiva in the world since formal study of musar texts was introduced to the yeshiva curriculum by the Mussar Movement of Rabbi Yisroel Salanter.
