Q: The halacha is that if one has kavanah during the first bracha of Shemonah Esrei but is sleeping through the rest of davening he’s yotzei. But if he has kavanah by all the brachos but sleeps through the bracha of Avos then he’s not yotzei. What’s so special about this first bracha?
Q: In one of your books you write that davening with Modern Orthodox people who aren’t serious about serving Hashem is compared to sha’atnez – a mixing that is unfavorable in the eyes of Hashem. But I thought that we are obligated to daven with all Jews – sinners as well?
