Over decades of teaching Torah and in thousands of shiurim, Rabbi Hershel Schachter has covered and taught the breadth and depth of Torah. One major theme that reverberates throughout his teachings is the centrality and role of Torah Shebe’al Peh, the Oral Torah. For the very first time, Rabbi Schachter presents in one volume the teachings of our Sages from across the generations, together with his own personal approach, regarding the Torah Shebe’al Peh, the halakhic process, and the importance of the Mesorah, the rabbinic Tradition.
