"Everything in the universe is forever changing. Tai chi chuan may appear slow and unhurried to an observer, but the movements flow together continuously, without pause. Architecturally speaking, a curved line can support much more weight than a straight line. Likewise, in tai chi chuan, speed is not the main objective. Balance and stability are more important. Push Hands practice is extremely important because it requires an acute ability to sense and become aware of mistakes and flaws in the opponent's moves. If he is making no mistakes, then create an opportunity for them to occur. It is imperative that your own moves be executed flawlessly. As long as the opponent intends to knock me over or attack me, then his weakness will be exposed. "Preserve gains and maintain stability. Modesty brings gain, arrogance yields loss." This is an essential aspect of the political and personal philosophy of Chinese people. It is much more important to be spared defeat than to defeat the other. As long as I myself am not defeated, it does not really matter if my opponent loses. If he does not handle himself well, he will eventually be defeated. If he does handle himself well, that is also fine."
