四分律刪繁補闕行事鈔 1.79

1.79

夫宅身佛海，餐味法流，形廁僧伍，行唯三位。若遵仰正戒，識達持犯，則中卷之中，體相具矣。自行既成，外德彰用，則上卷之中，綱領存矣。自他兩德，成相多途，則下卷之中，毛目顯矣。此三明行，無行不收；三卷攝文，無文不委。

Now, housing oneself within the ocean of the Buddha, tasting the flow of the Dharma, and numbering among the ranks of the saṃgha, practice consists of only three positions: If one reveres and upholds the correct precepts and thoroughly discerns observance and transgression, then within the middle roll, the essence and marks are fully provided. Once one's own practice is accomplished and outward virtue manifests its function, then within the upper roll, the main guidelines are preserved. As the accomplishments and marks of both self-benefiting and other-benefiting virtues have many paths, then within the lower roll, the fine details are revealed. These three illuminate practice, and no practice is not subsumed; the three rolls encompass the text, and no text is not thorough.
