Chapter 28, Part 8C - Chuang Tzu

The men of ancient times who had attained the Way were happy if they were blocked in, and happy if they could get through. It was not the fact that they were blocked or not that made them happy. As long as you have really gotten hold of the Way, then being blocked or getting through are no more than the orderly alternation of cold and heat, of wind and rain. Therefore Hsu Yu enjoyed himself on the sunny side of the Ying River, and Kung Po found what he wanted on top of a hill.
