Softness triumphs over hardness, feebleness over strength. What is more malleable is always superior over that which is immoveable. This is the principle of controlling things by going along with them, of mastery through adaptation.
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
