21.401

初一、趣向德，趣向涅槃故，二者、自體德，謂美妙顯了，三者、加行德，謂易解樂聞無依不違無邊等五，是其功能名為加行。

The first is the virtue of orientation, because it is oriented toward nirvāṇa. The second is the virtue of its own essence, meaning it is exquisite and distinct. The third is the virtue of preparatory application, meaning the five such as being easy to understand, delightful to hear, without dependence, non-contradictory, and boundless; these are its functions, called preparatory application.
