俱舍論記 4.58

4.58

「豈無經亦說有身輕安耶」者，經部難。豈無經亦說有身輕安，何故但說心輕安耶？經部計身輕安是觸事輕安，觸用風為體、為輕安，名通輕觸。故以為難。彼宗心輕安是心所，身輕安是輕觸。

"Do not sūtras also speak of bodily pliancy?": the Sautrāntika raises an objection. Do not sūtras also speak of bodily pliancy? Why do you speak only of mental pliancy? The Sautrāntika maintains that bodily pliancy is tactile pliancy; touch takes the wind element as its substance, and as pliancy, its name encompasses light touch. Therefore, they make this objection. In their school, mental pliancy is a mental factor, while bodily pliancy is light touch.
