This maamar is of particular interest because it was the first discourse delivered by the Previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn, of blessed memory, after succeeding to the mantle of leadership on Beis Nissan, 5780 (1920). It is based on the last discourse delivered by his father, the Rebbe Rashab, who passed away on that date. This maamar was first heard in the midst of the bitter civil war that shook the cities of Russia in the aftermath of the 1917 Revolution and the First World War.
