俱舍論記 4.61

4.61

「應知此中至身堪任性」者，上既難殺，論主依經部宗復為好解。應知此經中言身輕安者，身堪任性，輕安即是輕安風觸。此觸在身，於諸善法有所堪任。諸師多解此文是說一切有部答者，此解謬矣。應善思之。

"One should know that here... bodily serviceability": since the objection above pressed to an impasse, the author of the treatise, relying on the Sautrāntika school, provides a superior explanation. One should know that when this sūtra speaks of bodily pliancy, it means bodily serviceability; pliancy is precisely the tactile wind of pliancy. This touch is in the body, and is serviceable regarding wholesome phenomena. Many masters explain that this text is an answer from the Sarvāstivāda, but this explanation is mistaken. One should reflect on it carefully.
