When we die, we don’t go to heaven—we leave heaven.
The survival instinct in human beings is so great that we cannot imagine, even conceptually, that there could come a time when we, personally, would no longer exist. We can accept that we did not exist before we were born, but somehow not to exist once we have begun to exist—once we have been born—seems unimaginable. It seems like such a waste and a tragedy for our life not to go on in some form, in some other place—perhaps some better place. So we may want to idealize what that place and experience would be like, or let others do it for us. Life that would be eternal is greatly to be wished for. But it is only a wish. Our celestial bounty is actually to be found and savored in the present, here on Earth.
