Talking during davening. Wasnt a special Mi Shebaeirach composed for those who dont talk during davening, composed after Tach vTat by the Tosfos Yom Tov? Am I confusing several things?
Regarding learning during davening. How would it look to people if in the middle of Seder someone walked up to the Bimah and started davening. Why is it any more acceptable if in the middle of Tefilla someone stands near the Bima looking into a gemara. There is a time for tefilla and a time for learning. Why do we try and “chap” both at the same time.
About a year ago I heard repeated in the name of R” Chaim Kanievsky (I have no way to verify this statement, and apologies o the Rav if he never said it) that being Maaver Sedrah during chazoras HaShatz is a Mitzvah Habaa BiAveirah.
