Concept in East Asian philosophy (3)
I believe the answer is:
tao
'concept in east asian 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 "true path" , "In China, code of behaviour in harmony with natural order" , "religious way" , "Chinese philosophical principle" , "Philosophical principle, the way" .)
