Enlightenment (7)
I believe the answer is:
nirvana
'enlightenment' is the definition.
(I know that enlightenment can be written as nirvana)
This is the entire clue.
(Other definitions for nirvana that I've seen before include "Buddhist state of bliss; enlightenment" , "serene place" , "Buddhist state of perfect bliss" , "religious state" , "Eastern place of complete bliss" .)
