___ Buddhism (3)
I believe the answer is:
zen
'buddhism' is the definition.
(Zen Buddhism is an example)
This is all the clue.
(Other definitions for zen that I've seen before include "Japanese Buddhism" , "Form of Buddhism emphasising meditation and intuition" , "School of Buddhism" , "Form of Buddhism, emphasises meditation" , "Form of Buddhism that says meditation brings enlightenment" .)
