You felt something huge and marvelous of which you are part, and in the moments you described, you forgot yourself for you were one with your world and with the sky above it, and even the stars looking down. There is nothing larger or more wonderful than that. Still, there are those who would prefer self. They will accept any belief, no matter how foolish, if it guarantees them personal immortality. I know people like that. But there are others who know themselves well enough to realize how limiting that is.
