'caste inside worshipped as god no' is the definition.
I can't tell whether this defines the answer.

'longer restricted' is the wordplay.
'longer' becomes 'de' (I can't justify this - if you can you should believe this answer much more).
'restricted' becomes 'classified' (similar in meaning).
'de'+'classified'='DECLASSIFIED'
