As regards the quietude of the sage, he is not quiet because quietness is said to be good. He is quiet because the multitude of things cannot disturb his quietude. When water is still, one's beard and eyelashes are reflected in it. A skilled carpenter uses it in a level to obtain a measurement. If still water is so clear, how much more are the mental faculties! The mind of the sage is the mirror of heaven and earth in which all things are reflected.
ZhuangziTherefore, the truly great man, although he does not injure others, does not credit himself with charity and mercy (these are natural to him). He does not seek gain, but does not despise his followers who do. He struggles not for wealth, but does not take credit for leaving it alone... The ranks and emoluments of the world are to him no cause for joy, it's punishments and shame no cause for disgrace.
ZhuangziHence it demands the emptiness of all the faculties. And when the faculties are empty, then the whole being listens. There is then a direct grasp of what is right there before you that can never be heard with the ear or understood with the mind.
