大般涅槃經義記 5.194

5.194

下就此二破其所立，說心無常破前第三、第五、第六及與第七，以此四種就心計故說色無常，破前第四所想不滅，以此一種就色計故。

Below, based on these two, it refutes what they establish: speaking of the mind's impermanence refutes the earlier third, fifth, sixth, and seventh, because these four are conceptualised in terms of mind; speaking of form's impermanence refutes the earlier fourth, what is ideated not perishing, because this one is conceptualised in terms of form.
