俱舍論記 23.91

23.91

「智是解脫至驅賊閉戶」者，八智是解脫道，在生相時非惑得俱名正解脫，令至現在名已解脫惑得，與離繫得俱時起，故名解脫道。故《婆沙》云「諸解脫道唯名證滅，與離繫得俱現前故，無間道如驅賊，解脫道如閉戶。

Regarding "Cognition is liberation... like expelling a thief and shutting the door": The eight cognitions are paths of liberation. When they are in the state of arising, they are not concomitant with the possession of defilement and are called "being liberated"; when they are brought into the present, they are called "having been liberated from the possession of defilement," and because they arise simultaneously with the possession of disjunction, they are called paths of liberation. Thus the Mahāvibhāṣā says: "All paths of liberation are called only 'realizing cessation', because they manifest simultaneously with the possession of disjunction. The unobstructed path is like expelling a thief; the path of liberation is like shutting the door."
