俱舍論記 16.11

16.11

「豈不惡業果至名為白黑」者，問。豈不欲界惡業及果，亦為善業及果間雜相續起故，是則亦應名為白黑。此即以惡業果例善業果。

"Would not evil actions and fruits ... be called white-black?": a question. Would not desire-realm bad actions and fruits, also arising in continuity interspersed with wholesome actions and fruits, therefore also deserve to be called white-black? This uses evil actions and fruits to draw a parallel with wholesome actions and fruits.
