Wow. That's a great quote. Here's another on a similar theme....
Once upon a time, I, Chuang Chou, dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of my happiness as a butterfly, unaware that I was Chou. Soon I awaked, and there I was, veritably myself again. Now I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly, dreaming I am a man. Between a man and a butterfly there is necessarily a distinction. The transition is called the transformation of material things.

On Leveling All Things
BUTTERFLY'S DREAM
Otagaki Rengetsu (1791-1875)
Fluttering about sleepily
in a field of
dew-kissed flowers--
could it be the little butterfly
of Chuang-t'zu's dream?
