俱舍論記 2.81

2.81

「論曰至無別性故」者，眼等五界有異熟、有長養。此眼等五，同類因生亦是等流。今顯異門，廢總論別。離異熟、長養外無別性故，所以不說。

On the passage "The treatise says [...] because there is no distinct nature": The five elements of the eye and the rest have retribution and have nourishment. These five, such as the eye, arising from similar causes, are also outflows. Now, to make evident distinct perspectives, the general is set aside to discuss the particular. Because apart from retribution and nourishment there is no distinct nature, they are not mentioned.
