Today is Yud Shevat,marking 70 years of the Lubavitcher Rebbe’s leadership after the passing of the Previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak. The Rebbe was a leader, a nassi, for the entire Jewish nation, and in fact for the entire world. And he still continues to lead us, albeit on a more spiritual level. What is it we need to learn from the Rebbe? What he taught us in the first maamar he said, Basi L’gani: that we are the seventh generation from Avraham Avinu and all sevenths are beloved by virtue of being the seventh from the first.
