俱舍論疏 4.168

4.168

論「若有別體至俱時起故」，難也。麁、細一法上下不同，如何俱起？此經部宗不許有別體性。

On the Śāstra's [words], "If they had distinct substantial entities […] because they arise at the same time": this is an objection. How can gross and subtle, which are different grades within a single dharma, arise together? This Sautrāntika school does not accept that they have distinct substantial natures.
