I am curious too. Maybe he means the kind of motives like Indian people do, happy funerals.
However, to speak my mind, I think this aspect lies more in what the person was like, what he/she achieved, what you achieved with him/her and what was left unfinished. I have lost quite some people, and to this day I think: how they died, were they relieved or died with unsolved life, or from a miss?
I know there might not be an afterlife, and human body is just the body, a chemical compound, but still, as I live in presence, i do think about what was that persons last thought. I don't live in another life, nor in the past, i live in presence, and when someone is missing, I may miss.
