俱舍論疏 28.14

28.14

論「若謂令心至等持無用」，第二難也。若謂前念等持令心於第二念亦同前心緣一境轉，此即前心令其後心同一境轉，後心相應，等持何用？

The Śāstra states: "If it is said that it causes the mind... concentration is useless." This is the second objection. If it is said that concentration in the preceding moment causes the mind in the second moment also to proceed taking a single object identically with the preceding mind, then this is the preceding mind causing the subsequent mind to proceed on the identical single object; what is the use of concentration associated with the subsequent mind?
