Discussed more peaceful destiny (5)
I believe the answer is:
karma
'destiny' is the definition.
(karma is a kind of destiny)
'discussed more peaceful' is the wordplay.
I cannot quite understand how this works, but
'more' could be 'm' and 'm' is found within the answer.
The remaining letters 'kara' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for karma that I've seen before include "Retribution" , "Fate; result of one's past deeds" , "Buddhist concept of inevitable consequence" , "Hindu principle determining fate in re-incarnation" , "State according to past deeds" .)
