法華義疏 10.194

10.194

「佛言我亦如是」下，第三、合譬。但有三意：初、明不滅；「為眾生」下，明方便示滅；「亦無有能」，此辨不虛也。

From "The Buddha said: I too am like this" onward: third, the application of the parable. There are only three points: first, explaining non-extinction; from "For the sake of sentient beings" onward, explaining expediently displaying extinction; "nor can anyone [say]", this establishes non-falsehood.
