大般涅槃經義記 4.187

4.187

後觀法、僧，於中但明法之盛衰，僧隨法說更不別論，能興法者即是僧盛、能損法者即是僧衰，故不別說。文別有三：一明經法興廢所由；二「無有不求男子身」下就興廢時明經有力、無力之別；三「如過夏名秋」已下明廢興處。

Afterward, one contemplates the Dharma and Saṅgha; within this, it only clarifies the flourishing and decline of the Dharma, and the Saṅgha is explained following the Dharma without being treated separately. Those who can make the Dharma flourish are precisely the flourishing of the Saṅgha, and those who can harm the Dharma are precisely the decline of the Saṅgha; therefore they are not discussed separately. The text has three distinct parts: first, clarifying the causes of the flourishing and decline of the scriptural Dharma; second, from "There are none who do not seek a male body..." onward, clarifying the distinction between the scripture having power and having no power according to the times of flourishing and decline; third, from "Just as the passing of summer is called autumn..." onward, clarifying the places of decline and flourishing.
