After that first Maamar, the Rebbe stopped speaking about our mission and Moshiach, for the most part, and stared doing. The new ten twenty years the Rebbe spoke how we can’t be satisfied with just sitting in the beis medrash and worrying about our own spiritual growth when there is a fire of assimilation consuming our fellow Jews. We need to get out there and bring those Jews in. Instead of cutting ourselves off from the world e need to bring other Yidden back to yiddishkeit. That was the message the Rebbe pounded into his chassidim amongst many other important ones, such as how yiddishkeit is the true feminism- that one’s close to my heart:)
Then in the tof shin mems- 80s the Rebbe started sending lots of shluchim out and starting mitzvah campaigns like giving out Shabbos candles to women, it putting on Tefillin with men. Which was unheard of by the time. The idea was every mitzvah is precious no matter what came before or follows
