It's one of the saddest things that about the only certainty in life are ends. I don't think any amount or kind of words are adequate to help or alleviate this. But maybe, no one is ever truly gone as long as they live in the memories of those who carry them.
i like to believe the later but i also understand that energy can be transformed but not destroyed and that our essence that tiny iota of energy is always present here in the universe and all of who could experience deja vue have might have even been here before.
thank you .
