有義：既無別體，從他分說如何名實？雖不同觸以多法成，依實立愛名定假故。故知初因對界身足亦有不定，非正因也。

An opinion holds: 'Since it has no separate substance and is spoken of as a portion of something else, how can it be called real? Although it is not like contact which is composed of multiple dharmas, because craving is designated in dependence upon the real, it is definitively conventional. Therefore, one should know that the first reason, when opposed to the Dhātukāya, also has the fault of inconclusiveness and is not a valid reason.'
