Reply To: Chidushim on Daf Yomi

ברכות יח,ב

Shiva should be sat in the house where the niftar lived as he comes back to the place where he lived.
Every custom there indicates that we must rely on others and we are not an island.
The sudas havroah being provided with food is an example of this idea. The shiva call and davening in the
house of the niftar is anoth example. We cover the mirror to realize that we need others and not to see only
ourselves.
