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.
The Vinaya master said:
-Most people do that.
The Zen master...
Is the action of nature not unlike drawing a bow?
What is higher is pulled down, and what is lower is raised up;
What is taller is shortened, and what is thinner is broadened;
Nature's motion decreases those who have more than they need
And increases those who need more than they have.
It is not so with Man.
Man decreases those who need more than they have
And increases those who have more than they need.
