Hindu god central to skinny Sadhu morale (5)
I believe the answer is:
indra
'hindu god' is the definition.
(Indra is an example)
'central to skinny sadhu morale' is the wordplay.
'central' says to take the centre.
'sadhu morale' becomes 'dra' (I am not sure about this - if you are sure you should believe this answer much more).
The middle of 'skinny' is 'in'.
'in'+'dra'='INDRA'
Can you help me to learn more?
(Other definitions for indra that I've seen before include "Deity" , "Hindu king of the gods" , "Hindu god of the weather" , "Hindu god of rain and thunder - drain (anag)" , "One responsible for rain" .)
