Concept in Chinese philosophy (3)
I believe the answer is:
tao
'concept in chinese philosophy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tao that I've seen before include "Chinese way to be followed" , "Chinese philosophical principle" , "Source of existence (Chinese)" , "religious way" , "In China, code of behaviour in harmony with natural order" .)
