俱舍論疏 10.89

10.89

論「有說觸後至緣觸生受」，述經部宗上坐釋也。此師意說：後念識依前念根、境生。第一念根、境第二念識生，即於此時三和合觸。此觸即用三和為體，更無別法。至第三念方生受也。

On the Śāstra's statement: "Some say that after contact ... conditioning contact, feeling arises": this recounts the explanation of the elder of the Sautrāntika school. This master means: consciousness of the subsequent moment arises based on the faculties and objects of the preceding moment. In the first moment there are faculty and object; in the second moment consciousness arises, and precisely at this time the three unite in contact. This contact takes the union of the three as its essence, having no separate dharma apart from them. Only upon reaching the third moment does feeling arise.
