Ideal way to live one's life, in Chinese philosophy (3)

I believe the answer is:

tao

(Other definitions for tao that I've seen before include "Element of Chinese philosophy" , "In China, code of behaviour in harmony with natural order" , "Universal principle of Chinese philosophy" , "The way of Chinese philosophy" , "Chinese philosophical principle" .)

I've seen this clue in The Wall Street Journal.
