Would someone explain the requirements to daven (pray) in a minyan, when the minyan is needed and what can't one do absent a minyan? Where can I confirm this? Thanks.
Shulchan Aruch 90:9: Try to daven in shul. If he is "annus" and can't make it at least daven "together" with the congregation (at the same time). And if is "annus" and couldn't make it on time to the minyan at least daven by himself in the shul. Mishan Brura (28) explains the power of the davening together with a congregation: Hashem doesn't "moes" (dislikes?) the davening of a congregation.
