俱舍論疏 5.5

5.5

[On the] Śāstra['s statement]: "This again is of two kinds … because they equally possess each": Within this are two kinds: first, generic similarity of sentient beings; second, generic similarity of dharmas. Within the generic similarity of sentient beings, it is further divided into two: first, undifferentiated; second, differentiated. This text explains the undifferentiated: it means all sentient beings possess it equally, and it solely excludes insentient things, hence it is called undifferentiated.
