It (Tao) is eternally without desire. So, it can be called small. All things return to it, although it does not make itself their ruler. So, it can be called great.
LaoziYield and overcome; Bend and be straight; Empty and be full; Wear out and be new; Have little and gain; Have much and be confused. ...The ancients say, "Yield and overcome." Is that an empty saying? Be really whole, And all things will come to you.
Laozi
