If water derives lucidity from stillness, how much more the faculties of the mind! The mind of the sage, being in repose, becomes the mirror of the universe, the speculum of all creation.
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.
