"On Grief and Grieving"

I've been reading this book co-authored by David Kessler and Elisabeth Kubler-Ross, finished right before she died last year. There was one passage in particular that talked about how many people believe that we never die alone, and that all those we once knew will be there to greet us in death. At first the thought made me upset and angry, because who did Ashley know who had already died? But then I thought of my dad's father who died a few months before Ashley was born, and I could picture Ashley together with our grandfather. She would fill him in one what everyone has been up to for the past 26 years, and that image made me cry. I like to think that Ashley and my grandfather are together.
Another passage in the book talked about how we the living are constrained by time. It may be another 60 years before I see Ashley again, if I believe that everyone will be reunited in death, but the dead, who live in another realm, don't have time restrictions, so what may be 60 years for me may only feel like a matter of seconds to the deceased. Obviously nobody knows for sure what happens, and right now this is what feels good for me to believe.
