Obtain soul-stirring forgiveness (10)
I believe the answer is:
absolution
'forgiveness' is the definition.
(I've seen this before)
'obtain soul-stirring' is the wordplay.
'stirring' is an anagram indicator.
'obtain'+'soul'='obtainsoul'
'obtainsoul' anagrammed gives 'ABSOLUTION'.
(Other definitions for absolution that I've seen before include "discharge" , "Release from guilt" , "Forgiveness" , "acquittal" , "pardon" .)
