Mencius - Book 5, Part 1, Chapter 7C

'I have not heard of one who bent himself, and at the same time made others straight; how much less could one disgrace himself, and thereby rectify the whole kingdom? The actions of the sages have been different. Some have kept remote from court, and some have drawn near to it; some have left their offices, and some have not done so: that to which those different courses all agree is simply the keeping of their persons pure.

'I have heard that Î Yin sought an introduction to T'ang by the doctrines of Yâo and Shun. I have not heard that he did so by his knowledge of cookery.

'In the "Instructions of Î," it is said, "Heaven destroying Chieh commenced attacking him in the palace of Mû. I commenced in Po."'
