“The doctrine of the Second Coming has failed, so far as we are concerned, if it does not make us realize that at every moment of every year in our lives Donne's question "What if this present were the world's last night?"”
is equally relevant.

Breakfast of Champions (1973)
Context: I was on par with the Creator of the Universe there in the dark in the cocktail lounge. I shrunk the Universe to a ball exactly one light-year in diameter. I had it explode. I had it disperse itself again.
Ask me a question, any question. How old is the Universe? It is one half-second old, but the half-second has lasted one quintillion years so far. Who created it? Nobody created it. It has always been here.
What is time? It is a serpent which eats its tail, like this:
This is the snake which uncoiled itself long enough to offer Eve the apple, which looked like this:
What was the apple which Eve and Adam ate? It was the Creator of the Universe.
And so on.
Symbols can be so beautiful, sometimes.
