To realize that our knowledge is ignorance, This is a noble insight. To regard our ignorance as knowledge, This is mental sickness. Only when we are sick of the sickness Shall we cease to be sick. The Sage is not sick, being sick of sickness; This is the secret of health.
A great nation is like a great man:When he makes a mistake, he realizes it.Having realized it, he admits it.Having admitted it, he corrects it.He considers those who point out his faultsas his most benevolent teachers.He thinks of his enemyas the shadow that he himself casts.
The Tao doesn't take sides; it gives birth to both good and evil. The Master doesn't take sides; she welcomes both saints and sinners. The Tao is like a bellows: it is empty yet infinitely capable. The more you use it, the more it produces; the more you talk of it, the less you understand. Hold on to the center.
