Shunryu Suzuki on Living In The Dark, Empty Sky.

We should always live in the dark, empty sky.
The sky is always the sky.
Even though clouds and lightning come,
The sky is not disturbed.
Even if the flashing of enlightenment comes,
Our practice forgets all about it.
Then it is ready for another enlightenment.

Shunryu Suzuki, "Zen Mind, Beginner's Mind"
