「由變壞故至名色取蘊」者，答。可變可壞，故名為色。引證可知。又《婆沙》九十七云「問：變與壞有何差別？答：變者顯示細無常法，壞者顯示麁無常法。復次變者顯示剎那無常，壞者顯示眾同分無常。復次變者顯示內分無常，壞者顯示外分無常。復次變者顯示有情數無常，壞者顯示非情數無常，如說舍壞、倉庫等壞。

"Because it can be transformed and deteriorated (rūpyate) […] it is called the clinging-aggregate of matter": This is the answer. Because it can be transformed and deteriorated, it is called matter (rūpa). The citations of proof are self-evident. Furthermore, the Vibhāṣā, fascicle 97, says: 'Question: What is the difference between transformation (rūpaṇa) and deterioration? Answer: Transformation indicates subtle impermanence; deterioration indicates coarse impermanence. Furthermore, transformation indicates momentary impermanence; deterioration indicates the impermanence of the generic group (nikāya-sabhāga). Furthermore, transformation indicates the impermanence of internal elements; deterioration indicates the impermanence of external elements. Furthermore, transformation indicates the impermanence of sentient beings; deterioration indicates the impermanence of non-sentient things, as in speaking of the deterioration of houses, storehouses, and so forth.'
