Craze never included Buddhism (3)
I believe the answer is:
zen
'buddhism' is the definition.
(Zen is an example)
'craze never included' is the wordplay.
'included' indicates a hidden word (I've seen 'includes' mean this).
'ZEN' is hidden in the letters of 'craze never'.
(Other definitions for zen that I've seen before include "Branch of Buddhism" , "Form of Buddhism, emphasises meditation" , "Form of Buddhism that says enlightenment comes through meditation" , "Dibdin detective; Jap. Buddhism" , "Contemplative school" .)
