俱舍論疏 30.19

30.19

論「或補特伽羅至生世間故」，論主反難也。以經說一，即謂非蘊是別一我。經說於生，我應有為。違汝宗也。

On the Śāstra's statement: "Or else the pudgala [...] because it is born into the world": The author of the Śāstra counters with an objection. Because the sūtra says 'one,' you claim it is not the aggregates but a separate, single self. Since the sūtra speaks of 'birth,' the self would have to be conditioned, which contradicts your school's tenet.
