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.
ZhuangziIf you want to nourish a bird, you should let it live any way it chooses. Creatures differ because they have different likes and dislikes. Therefore the sages never require the same ability from all creatures. . . concepts of right should be founded on what is suitable. The true saint leaves wisdom to the ants, takes a cue from the fishes, and leaves willfulness to the sheep.
