大般涅槃經義記 4.7

4.7

In the second pair, 'if one says all conditioned phenomena are impermanent' cites the view of impermanence: this says that the dharmas of saṃsāra and nirvāṇa are both extinguished and annihilated, hence they are called 'impermanent'—it does not mean the impermanence of changing flux through before and after. 'This is the view of annihilation' concludes that annihilation differs from permanence. 'Conditioned phenomena are permanent' cites their view of permanence, meaning they say that all the conditioned phenomena of the five aggregates are permanent. 'This again is the view of permanence' concludes that permanence differs from annihilation.
