The love of a Sage for his fellows likewise finds expression amongst mankind. Were he not told sop, he would not know that he loved his fellows. But whether he knows it or whether he does not know it, whether he hears it or whether he does not hear it, his love for his is without end, and mankind cease not to repose therein.
ZhuangziThe hearing that is only in the ears is one thing. The hearing of the understanding is another. But the hearing of the spirit is not limited to any one faculty to the ear, or to the mind.
ZhuangziThe mind remains undetermined in the great Void. Here the highest knowledge is unbounded. That which gives things their thusness cannot be delimited by things. So when we speak of 'limits', we remain confined to limited things. The limit of the unlimited is called 'fullness.' The limitlessness of the limited is called 'emptiness.' Tao is the source of both. But it is itself neither fullness nor emptiness
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.
