Once a Zen master just set down to pronounce a sermon, when outside a bird started to sing. The master did not say a word and everybody listened to it.
When the bird stopped singing the master simply announced that the sermon was over, and he moved away.
-The Spirit of Zen, Lo Zen, by W. Watts
True creativity and alertness only arise when emptiness has seized the mind.
I am halfway there.
My mind is empty.
