大般涅槃經義記 6.216

6.216

四「迦葉佛法實不滅」下，對前第四明雖言滅，常存不變，故得名為諸佛祕藏。而中有二：一正明法體有滅、不滅；二「若我弟子受時」已下勸人受持，令使此經於人不滅。就明法體滅、不滅中，「如我上說唯有文殊乃解是義，今當重說，至心聽」者，牒舉向前有得中義，今欲就之明滅、不滅，是故重牒，勅聽許說。

Fourth, from "The Dharma of Kāśyapa Buddha is truly not extinguished" below, in response to the fourth clause above, he clarifies that although it is said to be extinguished, it constantly abides and does not change; hence it can be named the secret treasury of the buddhas. Within this, there are two parts: first, directly clarifying that the substance of the Dharma has that which is extinguished and that which is unextinguished; second, from "If my disciples receive it" below, encouraging people to receive and uphold it, so as to cause this sūtra not to be extinguished among people. Within clarifying that the substance of the Dharma has that which is extinguished and unextinguished, "As I said above, only Mañjuśrī understands this meaning; now I shall explain it again, listen with wholehearted attention" reiterates the meaning regarding the attained mentioned earlier; now wishing to clarify extinction and non-extinction in reference to it, he therefore reiterates it, enjoining him to listen and granting permission to preach.
