Rav Nosson Tzvi Finkel:
Every year Rav Nosson Tzvi would give a Shmuez on rosh hashana in each of the three places where the Mir had a minyan.
On the last year of his life the Rosh Yeshiva Got up and asked, “What shoould a person think about during Tekiyos”? The Rosh answered, “you should about somebody else”.
