大般涅槃經義記 10.81

10.81

第五番中，「如說虛空是可作法」舉他所立。「如說去」等，辨他所立。「一切作」下，徵令無常。於中，初法、次喻、後合。

In the fifth section, 'As it is said that space is a conditioned dharma' cites the opponent's position. 'As it is said: removing...' and so forth distinguishes the opponent's position. From 'All conditioned...' downward, it challenges it to be impermanent. In this, first is the dharma, next the analogy, and last the application.
