How have you all coped with facing the reality of our mortality?
I remind myself that I was dead once before - before I was conceived. I think of my future demise as simply a return to my non-existent state before conception. I do not grieve the time I did not exist before conception, so why should I be grieved about the time I will not exist when I die?
I will not miss out on anything when I die because I will be unconscious. To miss out on something you have to be conscious of the fact that that thing exists and you're not experiencing it. So I know I will not be missing out on anything when I die because I will not have the consciousness required to experience loss and missing out. We only think we'll be missing out because we look at our death through the eyes of the living. You have to resist that temptation and look at your death through the eyes of the dead.
The worst part about dying could be that it happens painfully. But don't we experience pain when we get sick but do not die? Haven't you been sick before, in pain? So why should the pain of dying be dreaded any more than the pain we have already experienced without dying?
Death does no harm to the dead. Death only grieves the living. Don't grieve over your own death. Grieve over the death of a loved one.
If there is any religion I will get behind, it's a rational, non-theistic religion that focuses on this subject of coping with our own mortality, overcoming the irrational fear of death. I believe that once we sit down and meditate carefully on what our death actually entails and how it actually will not affect us in any way, much of the irrational fear and anxiety surrounding our mortality disappears.
