Chapter 31, Part K - Chuang Tzu

"Rites are something created by the vulgar men of the world; the Truth is that which is received from Heaven. By nature it is the way it is and cannot be changed. Therefore the sage patterns himself on Heaven, prizes the Truth, and does not allow himself to be cramped by the vulgar.

"The stupid man does the opposite of this. He is unable to pattern himself on Heaven and instead frets over human concerns. He does not know enough to prize the Truth but instead, plodding along with the crowd, he allows himself to be changed by vulgar ways, and so is never content. Alas, that you fell into the slough of human hypocrisy at such an early age, and have been so late in hearing of the Great Way! "
