He 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.
