One day a Vinaya master asked a Zen master:
-How should one practice Tao?
The Zen master replied:
-Eat when you are hungry, sleep when you are tired.

When beauty is abstracted
Then ugliness has been implied;
When good is abstracted
Then evil has been implied.
So alive and dead are abstracted from nature,
Difficult and easy abstracted from progress,
Long and short abstracted from contrast,
High and low abstracted from depth,
Song and speech abstracted from melody,
After and before abstracted from sequence.
