瑜伽師地論略纂 12.69

12.69

先云〈翼品〉。〈翼品〉者，謂行四法，如鳥之翼，故名〈翼品〉。今即不然，謂先解行云入菩薩相，在家、出家二分皆修，依二分修故，說名為分，故言〈分品〉。其何故明分者？已入菩薩相，在家、出家皆得，故次後明。

Formerly it was called the "Chapter on Wings." "Chapter on Wings" meant practicing the four dharmas like the wings of a bird, and hence it was named "Chapter on Wings." Now this is not so; having previously explained practice as entering the characteristics of a bodhisattva, both householders and renunciants cultivate these two divisions; because they cultivate based on the two divisions, it is called divisions, and hence it is titled "Chapter on Divisions." Why are divisions clarified? Having already entered the bodhisattva characteristics, both householders and renunciants can attain them, and so it is clarified directly after.
