Hindu god of destruction (5)
I believe the answer is:
shiva
'hindu god of destruction' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shiva that I've seen before include "Major Hindu deity (the destroyer)" , "powerful deity" , "Destroyer goddess of Hinduism" , "Jewish period of mourning" , "Major Hindu god with third eye in middle of forehead" .)
