Iran, ancient or new, being given new life (13)
I believe the answer is:
reincarnation
'being given new life' is the definition.
(being reincarnated)
'iran ancient or new' is the wordplay.
'new' indicates anagramming the letters.
'iran'+'ancient'+'or'='iranancientor'
'iranancientor' is an anagram of 'REINCARNATION'.
(Other definitions for reincarnation that I've seen before include "Soul's rebirth in another body" , "revised version" , "Rebirth in a new body" , "Rebirth (of a soul)" , "Embodiment of a soul in a new form after death" .)
