There is one specific area that I want to call attention to. Meira”h had an exceptional koch in all of the Rebbe’s inyonim, but one specific area that stands out was the Torah of the Rebbe. A very large-scale project that he was involved in in the last year or so was digitizing all of the Rebbe’s Torah (and, to be honest, although he tried to explain it to me more than once, and he was very enthusiastic about it, I still don’t really understand what it means). And this was a result of his general involvement in the Torah of the Rebbe, and he was very closely involved with the Project Likutei Sichos as well.
I know that his friends, those who are capable, will carry on the monumental project. But everyone can resolve to increase, in some manner, their koch in the Torah of the Rebbe. If you haven’t yet joined the Project Likutei Sichos, maybe now is the time to join. If you joined, but, perhaps, your enthusiasm cooled off over time, maybe now is the time to re-apply yourself. [After all, this Shabbos is Parshas Zochor, when we remember Amolek, remember the אשר קרך – the way he tried to cool us off from every matter of kedusha. Amolek said: ‘Even if you’re going to do something good, take a chill, no reason to get so excited about it’. So, when we set out to obliterate the memory of Amolek, we have to see to it that our actual behaviour reflects the opposite!]
And, if you’re already learning sichos, perhaps you can be learning them better, deeper, more thoroughly. Get together with some friends, set up another shiur, another chavrusa. Increase the buzz! [I will bli neder try to do my tiny part as well: For a while I was giving an occasional shiur in some of these sichos, but then I felt I couldn’t anymore (or I convinced myself that I couldn’t anymore). But I am going to try to re-start those (FWIW)].
