《淮南子·原道训》
要知道这 道 尽管虚无至极，但却能满足万物之需求，时时变化却能使万物归返自身。这 道 又具备应付万物的大小长短之能力，所以当万物纷至沓来、淆乱腾踊时， 道 都能处置有序。
至无而供其求，时骋而要其宿；小大修短，各有其具；万物之至，腾踊肴乱而不失其数。
You should know that the Tao, although extremely empty and elusive, can satisfy the needs of all things. It changes from time to time and can return all things to themselves. The Tao also has the ability to deal with all things, regardless of their size, length, or shortness, so when all things are coming in droves, The Tao can handle them in an orderly manner.
