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.
LaoziReturning to the source is stillness, which is the way of nature. The way of nature is unchanging. Knowing constancy is insight.
LaoziIf you overesteem great men, people become powerless. If you overvalue possessions, people begin to steal. The Master leads by emptying people's minds and filling their cores, by weakening their ambition and toughening their resolve. He helps people lose everything they know, everything they desire, and creates confusion in those who think that they know. Practice not-doing, and everything will fall into place.
Laozi
