It was a momentous evening beginning on Sunday 19 Marcheshvan at 10:00 this week, seeing the many hundreds of people who attended, listening avidly to the keynote speaker, the Rosh Yeshiva, HaRav Eliezer Yehuda Finkel, and HaRav Nachman Leibowitz, also a Rosh Yeshiva. Especially moving was the fact that the audience was comprised of baalei batim from the business world who came to recharge their souls during a week of Yarchei Kalla Torah study under the sponsorship of the Yeshivas Mir. The event focused on the two hundredth year since the yeshiva's founding, commemorated by over two hundred laymen who were brought back to the study benches. This, it was pointed out, is the perpetuity of the yeshiva - the Torah.
