I don't think there is a way to describe the pain of death. The separation may not be permanent. The separated can reconcile. Even if they don't makeup, they have a chance to see each other again. It's a comfort to know that at least the person we love is alive and well. But death is not like that. We never get a chance to see the dead person again. We cannot hear the voice of the deceased. That's why the pain of death is not even comparable to the pain of separation.
