大般涅槃經義記 3.76

3.76

上來第一廣明四人正法時中弘護利益，自下第二嘆經殊勝。句別有四：前二嘆勝，令人信樂；後二學益，使人修習。就前二中，「是經流處即是金剛」寄處顯勝，處勝難壞故如金剛；「是中諸人亦如金剛」寄人顯勝，義同前釋。就後二中，初明學益，「若有生」下明不學損。於學益中，「若聽不退」成因益也，「所願悉得」得果益也，「汝等應」下結勸受持。不學損中，先明不聽，「甚可憐愍」，失大損也，「何以」下釋。

The above is the first part, which explains in detail the benefits of propagating and protecting [the Dharma] during the era of the True Dharma by the four persons. The second part below praises the excellence of the sūtra. There are four distinct clauses: the first two praise its excellence, causing people to have faith and rejoice; the latter two [explain] the benefits of studying it, causing people to practice it. Within the first two: "the place where this sūtra circulates is just like vajra" relies on the place to reveal its excellence, because the place is superior and indestructible, and thus like vajra; "the various persons therein are also like vajra" relies on the persons to reveal their excellence, the meaning being the same as the previous explanation. Within the latter two: the first explains the benefits of studying, and from "if there are [living beings]" downward explains the harms of not studying. Among the benefits of studying, "if they listen without falling back" establishes the benefit of the cause; "all that they wish for will be obtained" establishes the benefit of the fruit; from "you all should" downward concludes by exhorting them to accept and uphold it. Among the harms of not studying: it first explains that not listening is "most pitiable," which is the harm of a great loss; from "why is that" downward explains it.
