I was taught that neshamos are learning in shomayim. I was also taught that those who were osek in the community are able to “keep watch” over the community, and those who were osek in the well being of their families are able to “keep watch” over their families. Obviously I don’t know what that really means, and I have to assume there are others who teach differently, but for my self this was very comforting information. It helps me believe that my parents and sisters are able to daven for me and my family down here.
