俱舍論疏 10.13

10.13

論「云何知然」，問也。自此已下第二別證有體所以。知體非異於明及是明無。

The treatise asks: "How is this known to be so?" This is a question. From here below is the second part, separately proving why it has a substantial entity, showing that its entity is not merely different from clarity nor the non-existence of clarity.
