大般涅槃經集解 12.22

12.22

案僧亮曰：滅是斷苦之術，故名師也。上說涅槃常故佛常，未明涅槃所以而常，重明之也。僧宗曰：上已佛教，今就理釋。以常師圓極，此理湛然，隱顯為異。及人會時，非為始起。人既秉法，法既是常，人豈無常耶？明駿案：第四階舉所師之法為證也。

Sengliang states: "Extinction is the method of severing suffering, hence it is called teacher. Above it was said that because nirvāṇa is permanent, the Buddha is permanent; since it had not yet clarified why nirvāṇa is permanent, he clarifies it again." Sengzong states: "Above he explained the Buddha's teaching; now he explains according to principle. Because the permanent teacher is perfect and ultimate, this principle is calm and clear, differing only in being concealed or revealed. When persons encounter it, it is not newly arisen. Since persons uphold the Dharma, and the Dharma is permanent, how could the persons be impermanent?" Mingjun notes: "The fourth step adduces the Dharma taken as teacher as proof."
