Confucius. Book 3, Chapter 8.
Book 3, Pa Yih.
1. Tsze-hsia asked, saying, "What is the meaning of the passage ‹ 'The pretty dimples of her artful smile! The well-defined black and white of her eye! The plain ground for the colors?' "
2. The Master said, "The business of laying on the colors follows (the preparation of) the plain ground."
3. "Ceremonies then are a subsequent thing?" The Master said, "It is Shang who can bring out my meaning. Now I can begin to talk about the odes with him."
