俱舍論疏 26.130

26.130

論「由此應言至皆名行相」，論主述自釋。言行相者，境相品類差別不同，故言行相。或是能取境差別相，故名行相。

The Śāstra states: "Therefore one should say... are all called aspects": the author of the treatise recounts his own explanation. As for "aspects," the modes and categories of objective characteristics are varied and not identical, hence called "aspects." Or, they are the distinctive characteristics of the object that can be apprehended, and are therefore called "aspects."
