俱舍論記 1.186

1.186

「復有別釋至理得成就」者，論主第二釋通外難。五識二依，或有變礙、或無變礙，以不定故不名色。無表一依，唯有變礙，以決定故說名為色。前難不齊，變礙名色得理成就。

"There is also another explanation... the principle is thereby established": here the author of the treatise provides a second explanation to resolve the external objection. The two supports of the five consciousnesses may either have mutability and resistance or lack mutability and resistance; being indeterminate, they are not called form. The single support of the non-revelatory [form] has solely mutability and resistance; being determinate, it is called form. The previous objection is unequal, and defining form by mutability and resistance is reasonably established.
