All existing things are really one. We regard those that are beautiful and rare as valuable, and those that are ugly as foul and rotten. The foul and rotten may come to be transformed into what is rare and valuable, and the rare and valuable into what is foul and rotten.
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
ZhuangziMen of this world all rejoice in others being like themselves, and object to others not being like themselves.
ZhuangziYou cannot speak of ocean to a well-frog, the creature of a narrower sphere. You cannot speak of ice to a summer insect, the creature of a season.
ZhuangziWhen an archer is shooting for nothing, he has all his skill. If he shoots for a brass buckle, he is already nervous. If he shoots for a prize of gold, he goes blind or sees two targets - He is out of his mind! His skill has not changed. But the prize divides him. He cares. He thinks more of winning than of shooting- And the need to win drains him of power.
