俱舍論記 5.245

5.245

「得及諸相至等流異熟」者，別解得及四相。五類分別，通剎那、等流、異熟，苦法忍俱故有剎那，同類因生故是等流，不善、善有漏生故是異熟。非極微故非所長養，非無為故非實。

"Possession and the characteristics […] uniform outflow and maturation:" this individually explains possession and the four characteristics. In the analysis of the five classes, they extend to the instantaneous, uniform outflow, and maturation: because they are simultaneous with the receptivity to the dharma of suffering (duḥkha-dharma-jñāna-kṣānti), there is the instantaneous; because they arise from a homogeneous cause, they are uniform outflow; because they arise from unwholesome or wholesome with outflows, they are maturation. Because they are not subtle atoms, they are not nourished; because they are not unconditioned, they are not real.
