To know how little one knows is to have genuine knowledge. Not to know how little one knows is to be deluded. Only those who know when they are deluded can free themselves from such delusion. The intelligent people are not deluded, because they know and accept their ignorance as ignorance, and thereby have genuine knowledge.
The Tao can't be perceived. Smaller than an electron, it contains uncountable galaxies. If powerful men and women could remain centered in the Tao, all things would be in harmony. The world would become a paradise. All people would be at peace, and the law would be written in their hearts. When you have names and forms, know that they are provisional. When you have institutions, know where their functions should end. Knowing when to stop, you can avoid any danger. All things end in the Tao as rivers flow into the sea.
A skillful commander is not overbearing. A skillful fighter does not become angry. A skillful conqueror does not compete with people. One who is skillful in using men puts himself below them. This is called the strength to use men. This is called matching Heaven, The highest principle of old.
Clay is moulded to make a vessel, but the utility of the vessel lies in the space where there is nothing. . . . Thus, taking advantage of what is, we recognize the utility of what is not.
Heaven's Way is like stretching a bow. The high is lowered and the low is raised. Excess is reduced and deficiency is replenished. Heaven's Way reduces excess and replenishes deficiency. People's Way is not so. They reduce the deficient and supply the excessive.
Without going outside, you may know the whole world, without looking through the window, you may see the ways of heaven. The farther you go, the less you know. Thus the sage knows without traveling; he sees without looking; he works without doing.
Heaven is eternal and Earth everlasting. They can be eternal and everlasting because they do not exist for themselves, And for this reason can exist forever.
