'ripped to pieces' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.

'to gather pictures' is the wordplay.
'gather' becomes 'reap' (reaping is a kind of gathering).
'pictures' becomes 'art'.
'to'+'reap'+'art'='TORE APART'

'being' is the link.
