俱舍論疏 10.14

10.14

論「說行緣故」，答也。答中有二：一略答、二廣答。此略答也，說行緣故。既是行緣，明知非是異明餘一切法，亦非無體，是明無也。

The treatise says: "Because it is spoken of as the condition for formations." This is an answer. Within the answer there are two parts: first, a brief answer; second, an extensive answer. This is the brief answer: because it is spoken of as the condition for formations. Since it is the condition for formations, one clearly knows that it is not all other phenomena different from clarity, nor is it devoid of substantial entity as the mere absence of clarity.
