Spiritual enlightenment about origin (7)
I believe the answer is:
rebirth
'spiritual enlightenment' is the definition.
(I've seen this before)
'about origin' is the wordplay.
'about' becomes 're' (regarding).
'origin' becomes 'birth' (I've seen this before).
're'+'birth'='REBIRTH'
(Other definitions for rebirth that I've seen before include "Start of a new life?" , "second coming" , "Renascence" , "Spiritual renewal" , "spiritual enlightenment" .)
