Sorrow and happiness are the heresies of virtue; joy and anger lead astray from TAO; love and hate cause loss of virtue. The heart unconscious of sorrow and happiness - that is perfect virtue. One, without change - that is perfect repose. Without any obstruction - that is the perfection of the unconditioned. Holding no relations with the external world, - that is perfection of the negative state. Without blemish of any kind, - that is the perfection of purity.
ZhuangziWhen I talk about having good hearing, I don't mean just listening, but listening to yourself. When I talk about good eyesight, I don't mean just looking, but looking at yourself.
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.
