瑜伽師地論略纂 4.81

4.81

「無罪、有罪、應修、不應修」者，散釋於因，善惡之體。　「黑、白、雜」者，釋果之體。果有黑白二分，故名有分。此十九中，有通俱生，或分別起，世、事、業果等，通二門故。

Regarding "faultless, faulty, to be cultivated, not to be cultivated": these loosely explain causes, the entities of good and evil. Regarding "black, white, mixed": these explain the entities of effects. Because effects have both black and white divisions, they are called "having divisions." Among these nineteen, some apply to both innate and conceptually differentiated [forms], because time periods, matters, karma, effects, and so forth apply to both categories.
