Here's one of the more famous passages from the Zhuangzi as told in the translation we used (The Essential Chuang Tzu, by Sam Hamill and J. P. Seaton):
> Long ago, Chuang Chou dreamed he was a butterfly fluttering among trees, doing as he pleased, completely unaware of a Chuang Chou. A sudden awakening, and there, looking a little out of sorts, was Chuang Chou. Now, I don't know whether it is Chou who dreamed he was a butterfly, or whether a butterfly dreams he's Chuang Chou. But between Chuang Chou and the butterfly, we ought to be able to find some sort of distinction. This is what's known as Things Changing.
