This is a foundational discourse for the Rebbe, because it was the last discourse prepared by the Previous Lubavitcher Rebbe, Rabbi Yosef Yitzhak Schneersohn, which he wanted studied by his followers on 10 Shevat (20 January), the Yahrzeit of his paternal great-grandmother Rivkah, in 1950. On that day he himself passed away. Every year his successor, his son-in-law Rabbi Menachem Mendel Schneerson, would teach a discourse with the same theme, focusing on one chapter of the original. The 1962 discourse focused on chapter12.
