A Halacha That’s Clear-Cut

In the eighth volume of the Igros Moshe, there is a fascinating teshuvah written to Rav Efraim Greenblatt, zt”l. This teshuvah, which is the 20th one in the sefer, comprises many varied and disparate topics. The teshuvah begins with a discussion of folding one’s tallis on Shabbos and then moves on to the recitation of Shehechiyanu on Chanukah, using hot water on Shabbos, eating turkey on Thanksgiving, the muktzeh status of sunflower seed shells, opening a store on chol hamoed, the punishment for embarrassing someone publicly, the obligation for a rav to issue halachic rulings, the correct position to be in while reciting havdalah, the explanation behind Rav Moshe’s, zt”l, peculiar practice during Tachanun, and on and on.
The twenty-first topic discussed in that one teshuvah is the mitzvah of comforting mourners. It is a common custom that before departing from the house of the mourning, the visitor blesses the mourner(s): “May Hashem comfort you among the other mourners of Zion and Jerusalem.” Rav Moshe, zt”l, discusses the significance of this declaration.
