Chapter 33, Part 2A - Chuang Tzu

To teach no extravagance to later ages, to leave the ten thousand things unadorned, to shun any glorification of rules and regulations, instead applying ink and measuring line to the correction of one's own conduct, thus aiding the world in time of crisis - there were those in ancient times who believed that the "art of the Way" lay in these things. Mo Ti and Ch'in Hua-li heard of their views and delighted in them, but they followed them to excess and were too assiduous in applying them to themselves.
~ Burton Watson translation via Terebess Asia Online ~
