Krishna is one crossword setter being talked about (6)
I believe the answer is:
avatar
But I can't explain it at all! Could you help me understand?
(Other definitions for avatar that I've seen before include "Figure representing a person, in a computer game say" , "Person who embodies a particular ideal" , "Cyberspace representation of a person" , "Manifestation of a deity (Hinduism)" , "Divine incarnation" .)
