Connie, I would not think of it as ‘rotting away’. True, nothing can stay intact and perfect forever, but if nothing else, the natural processes will break the Bible and pictures and notes down, along with your father’s remains. Ultimately, in a way, those things will all join and be mingled with him, one way or another. Think of it as the physical manifestation of how your memories and feelings about him are a part of you, carried in your mind and heart. When my father-in-law died, our family put all manner of things in the casket with him. Why? Because they were things he had liked in life, and we wanted him to have nice things. Yes, it’s silly from a rational standpoint, but if those things go with him and become a part of him, in a sense, then I suppose we will always be with him, just as he will always be with us in our memories. Maybe that’s really why we humans have come to do such things. It’s never wrong to show respect and love to people. Just remember to treasure your loved ones while they are still alive, too. It’s easy to take people for granted.
