俱舍論疏 6.63

6.63

On the Śāstra's statement: "If so, as [mentioned] before... should be mutual causes": this is the Sautrāntika's objection. If you claim that 'when one exists, all exist' proves mutual cause and effect, then according to what was cited before regarding phenomena that 'do not become causes by virtue of being coexistence causes'—where it states that derived matters are inseparable from one another, and derived matters, the primary elements, and the secondary characteristics are all inseparable from their underlying phenomena—they ought to be mutual causes.
