大般涅槃經集解 10.171

10.171

案僧宗曰：此第四段也。上明通經，此明通律也。寶亮曰：此顯流通處也。雜僧者，以善惡無作共成此人，故名為雜。但自持戒，不知他事，名愚癡也。清淨者，以二緣難壞，一則不求名、二則不違法律也。雜僧可壞，亦有二緣，一則為名利故研精所受；二者若遇善友，亦能壞惡而從善也。舉此二眾明力能降伏，下出五法為降伏之方法也。

Sengzong comments: This is the fourth section. Above, propagating the sūtras was clarified; here, propagating the Vinaya is clarified. Baoliang says: This reveals the place of dissemination. 'Mixed saṃgha': because non-informative karma of good and evil jointly form this person, they are called mixed. Merely keeping precepts oneself without knowing other matters is called foolish. 'Pure': hard to corrupt due to two conditions: first, not seeking fame; second, not violating the Dharma and Vinaya. The mixed saṃgha can be corrupted, also due to two conditions: first, for the sake of fame and profit they study what they received; second, if they meet good friends, they can also break evil and follow good. Presenting these two communities clarifies that the power is capable of subduing them; below, five dharmas are set forth as methods of subjugation.
