The universe is, instant by instant, recreated anew. There is in truth no past, only a memory of the past. Blink your eyes, and the world you see next did not exist when you closed them. Therefore, the only appropriate state of the mind is surprise. The only appropriate state of the heart is joy. The sky you see now, you have never seen before. The perfect moment is now. Be glad of it.

Around him Feegles started to wail and cower and Big Yan began to bang his head on the rear wall of the dairy.
