The 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
ZhuangziWhen you're dreaming, you don't know it's a dream. You might even interpret a dream in your dream - and then wake up and realize it was all a dream. Perhaps a great awakening will reveal this to be a dream as well.
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.
ZhuangziHe who dreams ... does not know he is dreaming... . Only when he awakens does he know he has dreamt. But there is also the great awakening (ta-chiao), and then we see that [everything] here is nothing but a great dream. Of course, the fools believe that they are already awake-what foolishness! Confucius and you, both of you, are dreams; and I, who tell you this, am also a dream.
