TaoTe Ching

Understanding others is knowledge,

Understanding oneself is enlightenment;

Conquering others is power,

Conquering oneself is strengh;

Contentment is wealth,

Forceful conduct is willfulness;

Not losing one’s rightful place is to endure,

To die but not be forgotten is longevity.

• Lao Tzu. Tao Te Ching 77
