四分律行事鈔資持記 2.267

2.267

初答盡中。配戒種類，文出多宗；《戒疏》、《義鈔》竝引；止以四重，攝一切戒。種名乃通，諸篇條相各自為種；類名則局，唯據殘下諸聚，是種之類。今明種類，且約偏對；種即四重，根本異故；類即餘篇，枝條生故；縱有無量，不出此四。

In the first answer stating that they are exhausted: correlating the precepts into kinds (zhong) and categories (lei), the text originates in the Sarvāstivāda school; both the Precept Commentary and the Meaning Manual cite it; it uses only the four pārājikas to subsume all precepts. The name "kind" (zhong) is general, with the respective article-marks of the various categories each being a kind; the name "category" (lei) is restricted, referring only to the various classes from saṃghāvaśeṣa downward, which are categories of the kinds. Now, in explaining kinds and categories, it is provisionally based on a specific correlation: "kinds" are the four pārājikas, because their roots are distinct; "categories" are the remaining chapters, because they arise as branches; even if there were an infinite number, they would not exceed these four.
