Once Chuang Chou dreamt he was a butterfly, a butterfly flitting and fluttering around, happy with himself and doing as he pleased. He didn't know he was Chuang Chou. Suddenly he woke up and there he was, solid and unmistakeable Chuang Chou. But he didn't know if he was Chuang Chou who had dreamt he was a butterfly, or a butterfly dreaming he was Chuang Chou.
ZhuangziCalculate what man knows and it cannot compare to what he doesn't know. Calculate the time he is alive and it cannot compare to the time before he was born. Yet man takes something so small and tries to exhaust the dimensions of something so large!
ZhuangziAs regards the quietude of the sage, he is not quiet because quietness is said to be good. He is quiet because the multitude of things cannot disturb his quietude. When water is still, one's beard and eyelashes are reflected in it. A skilled carpenter uses it in a level to obtain a measurement. If still water is so clear, how much more are the mental faculties! The mind of the sage is the mirror of heaven and earth in which all things are reflected.
ZhuangziThe effect of life in society is to complicate and confuse our existence, making us forget who we really are by causing us to become obsessed with what we are not.
ZhuangziAll men know the use of the useful, but nobody knows the use of the useless. Where can I find a man who has forgotten words so that I can have a word with him?
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
