Eastern path (3)
I believe the answer is:
tao
'eastern path' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tao that I've seen before include "religious way" , "Element of Chinese philosophy" , "Chinese way to be followed" , "Universal principle of Chinese philosophy" , "In China, code of behaviour in harmony with natural order" .)
