Four years ago my mom took her final breath, died, passed away. There are myriad ways of saying it. Died feels final and clinical; final breathe softens it. For me, however, passing away feels more like what my mom did, but I want to add ‘to a better place’, whatever that means? I don’t know, no one knows, but many of us believe that something beyond this earthly exist, and that it is good. Christianity declares it, and those of other faiths, as well as agnostics and atheists, have a sense that death is not final. For many believing that death is a big black hole is too frightening. For everyone, there are the memories.
As a Christian I want to add that I definitely believe that physical death is not the end. I have no idea what this means or what it is like, other than to say that it is of the spirit, not of the mind/body. Afterlife is not for the living to know, understand or experience. Having hope and faith is enough. It is the peace of God that passes all understanding.
