成唯識論述記 4.558

4.558

述曰：上來難訖。次下第二經部救云：此定加行但厭受、想，受、想能於靜慮、無色修行勝故。於此定中唯受、想滅非餘思等。有伏難彼云：何故唯受、想二名為心行，乃復滅之？思等不名，乃復不滅？

The Commentary states: Above, the objection was completed. Next below, the second, the Sautrāntika rescues [its position], saying: The preparatory practice for this absorption feels aversion only toward vedanā and saṃjñā, because vedanā and saṃjñā are preeminent in the cultivation of the dhyānas and formless [attainments]. In this absorption, only vedanā and saṃjñā cease, not other [dharmas] such as cetanā. There is a latent objection to them: Why are only the two, vedanā and saṃjñā, called mental activities and consequently ceased, while cetanā and the rest are not so named and consequently do not cease?
