Appetite for food and sex is nature.

When the people of the world all know beauty as beauty, There arises the recognition of ugliness. When they all know the good as good, There arises the recognition of evil.

Weapons are not proper instruments for gentle people; they use them only when they have no other choice. Peace and quiet are what they value. They do not glory in victory.

The Way is eternal. Until your last day, you are free from peril.

To become learned, each day add something. To become enlightened, each day drop something

Nature is not human hearted.

The Tao is like a well; used but never used up.
