俱舍論疏 10.110

10.110

論「又契經言至而不名觸」，此是第二責違經也。經言三和，如何觸、受位識非三和合？受位三和而不名觸？

On the Śāstra's statement: "Furthermore, the sūtra says ... yet not be called contact": this is the second, reproaching for contradicting the sūtra. The sūtra speaks of the union of the three; how could consciousness at the stages of contact and feeling not be the union of the three? Or how could the union of the three at the stage of feeling not be called contact?
