俱舍論疏 10.78

10.78

論「云何二法至義可成立」，經部責也。生既同時，於俱有法如何有力？受若未生，觸亦未有，如何生受？觸若已生，受亦已生，已生之法有何功能觸生於受？

On the Śāstra's statement: "How can two dharmas ... the principle be established?": this is the Sautrāntika's objection. If their arising is simultaneous, how can there be efficacy with respect to co-existent dharmas? If feeling has not yet arisen, contact does not yet exist either; how could it produce feeling? If contact has already arisen, feeling has also already arisen; what function could an already arisen dharma have for contact to produce feeling?
