I know the joy of fishes in the river through my own joy, as I go walking along the same river.
ZhuangziThe non-action of the wise man is not inaction. It is not studied. It is not shaken by anything. The sage is quiet because he is not moved, not because he wills to be quiet. . . . Joy does all things without concern. For emptiness, stillness, tranquillity, tastelessness, silence, and non-action are the root of all things.
