10.91

「無如是失至無非是觸」者，經部通難。無如是失，因前第一念根、境同時觸故，後第二念觸位受生，故諸觸起時必皆悉有受。此釋初難。第三念受同時所有識體無非是觸，以識起時必依於根緣境起故，此三名觸。此觸雖不能生同時受，而能生後第四念受。此釋後難。

Regarding "There is no such fault … none are not contact": the Sautrāntika resolves the objection. There is no such fault: because of the contact simultaneous with sense faculty and object in the prior first moment, feeling arises at the stage of contact in the subsequent second moment; therefore, whenever any contact arises, it must entirely have feeling. This resolves the first objection. None of the entities of consciousness simultaneous with feeling in the third moment are not contact, because when consciousness arises, it must arise relying on the sense faculty and taking the object as condition; these three are called contact. Although this contact cannot produce the simultaneous feeling, it is capable of producing the feeling of the subsequent fourth moment. This resolves the latter objection.
