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

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.
