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.
LaoziMan, when living, is soft and tender; when dead, he is hard and tough. All animals and plants when living are tender and delicate; when dead they become withered and dry. Therefore it is said: the hard and tough are parts of death; the soft and tender are parts of life.
Laozi
