俱舍論疏 10.102

10.102

論「謂有三地至名大地法」，經部答也。有三種三地，若法遍此三種三地名大地法，非是要遍一切心品。

On the Śāstra's statement: "It refers to having three grounds ... called an omnipresent mental factor": the Sautrāntika answers. There are three kinds of threefold grounds; if a dharma pervades these three kinds of threefold grounds, it is called an omnipresent mental factor, not that it must pervade all mental states.
