Feeling of immense rapture (7)
I believe the answer is:
ecstasy
'feeling of immense rapture' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ecstasy that I've seen before include "State of euphoria or dangerous drug" , "State of euphoria and drug that induces it" , "Overwhelming joy" , "transport" , "State of clated bliss" .)
