成唯識論述記 10.157

10.157

述曰：十一、三學相攝門。於中初出學名體第二，五位分別；第三，正以學攝度。戒學有三，初以七眾戒為體；二、以有為、無為無漏善法為體，有漏善法非正應修，體可斷故；三、謂正利樂三業為性，如上應知。

The Commentary states: Eleventh, the section on the mutual subsumption with the three trainings. In this, first the names and essences of the trainings are presented; second, they are distinguished in terms of the five stages; third, the trainings correctly subsume the perfections. The training in moral discipline has three types: first, it has the precepts of the seven assemblies as its essence; second, it has conditioned and unconditioned untainted wholesome dharmas as its essence—tainted wholesome dharmas are not what should properly be cultivated, because their essence can be abandoned; third, it has as its nature the three kinds of action that correctly benefit and gladden [others], as should be understood from what has preceded.
