I wonder: Do souls see and remember? Are they aware of what goes on among the living? Do they have feelings? Are they close with God? Do they only see and connect with people they love? Does this connection last for eternity?
In Judaism, I believe, everyone ought to have a funeral – not only for themselves, but also for those they leave behind. Sometimes it’s because they think they don’t deserve it. Perhaps there have been difficulties in their family relationships that they regret, or they simply are overly humble about anyone caring about them at their advanced age.
