大般涅槃經集解 18.225

18.225

案道生曰：以其遂謂不存，乃說我以悟之。既理顯身中，亦是語知顯也。僧亮曰，第二譬也。法有不空，亦有常我，不如所見一切苦也。僧宗曰：第四譬也。依教而行，已斷重倒。今常機且發，解釋佛果所以為常，此是物情所安，如慰問也。寶亮曰：此下第四譬眾生根熟，堪聞常住，即涅槃經教為慰喻之辭也。

Daosheng comments: Because he ultimately thought it did not exist, the doctor spoke of the self in order to awaken him. Since the principle is manifested within the body, it is through words that one knows it is manifest. Sengliang comments: This is the second metaphor. Among dharmas, some are non-empty, and there is also an eternal self; it is not as he saw, that everything is suffering. Sengzong comments: This is the fourth metaphor. Having practiced in accordance with the teaching, he had already severed severe inversions. Now the capacity for permanence is about to unfold, explaining why the Buddha-fruit is permanent. This is what sets worldly minds at ease, like comforting and consoling him. Baoliang comments: From here below is the fourth metaphor, illustrating that sentient beings' faculties have matured, and they are capable of hearing of eternal abiding; that is, the teachings of the Nirvāṇa Sūtra serve as words of comforting and consoling.
