Q. Dear Rabbi, I remember reading in the name of Rabbi Avigdor Miller zt’l how important it is always not to rush into anything one is about to start, even mitzvos as going to Shul or a Simcha. Before all, he advises, one should take a pause and think of what is about to happen and the negative possibilities that can occur. Giving echo to the words of the Sages “Wise is the one that can foresee what may happen.”
So when one enters Shul in the morning to daven, should he not do so with “Zerisus” as one is supposed to do when doing al mitzvos?
A. Horav Shlomo Miller’s opinion is that Halacha also requires that one should stop a bit before entering a Beis Hamedresh or Shul and reflect on what he is about to do.
After all,’Watchfulness brings to Eagerness’; (Avoda Zara 20b).
