Joy, anger, sorrow, happiness, find no place in that man's breast; for to him all creation is ONE. And all things being thus united in ONE, his body and limbs are but as dust of the earth, and life and death, beginning, and end, are but as night and day, and cannot destroy his peace. How much less such trifles as gain or loss, misfortune or good fortune?
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.
