Chapter 33, Part 1C - Chuang Tzu

How thorough were the men of ancient times!-companions of holiness and enlightenment, pure as Heaven and earth, caretakers of the ten thousand things, harmonizers of the world, their bounty extended to the hundred clans. They had a clear understanding of basic policies and paid attention even to petty regulations - in the six avenues and the four frontiers, in what was great or small, coarse or fine, there was no place they did not move.

The wisdom that was embodied in their policies and regulations is in many cases still reflected in the old laws and records of the historiographers handed down over the ages. As to that which is recorded in the Book of Odes and Book of Documents, the Ritual and the Music, there are many gentlemen of Tsou and Lu, scholars of sash and official rank, who have an understanding of it.

The Book of Odes describes the will; the Book of Documents describes events; the Ritual speaks of conduct; the Music speaks of harmony; the Book of Changes describes the yin and yang; the Spring and Autumn Annals describes titles and functions.
