大般涅槃經義記 5.319

5.319

後二門中皆初徵問，後辯可知。「以是義」下就人辯定，「以是義故名四無量，非諸聲聞、緣覺所知，乃是諸佛如來境界」辯大異小。以是「亦緣亦自在」者，在佛、菩薩，不在餘故，非二乘知，是如來境。「如是四」下辯小異大。於中初言「聲聞、緣覺雖名無量，少不足言」分小異大，「諸佛菩薩則得名為無量無邊」明大異小。領解可知。

In the latter two categories, there is first an inquiry and then an explanation, as can be known. From "for this reason" onward determines it with reference to persons: "For this reason they are called the four immeasurables; they are not what all śrāvakas and pratyekabuddhas know, but are the realm of all buddha-tathāgatas" distinguishes the Mahāyāna as different from the Hīnayāna. Because having "both an object and sovereignty" resides in buddhas and bodhisattvas and not in others, it is not known by the two vehicles, but is the realm of the Tathāgata. From "such four" onward distinguishes the Hīnayāna as different from the Mahāyāna. Within this, first saying, "Although śrāvakas and pratyekabuddhas are called immeasurable, being few they are not worth speaking of" demarcates the Hīnayāna as different from the Mahāyāna; "all buddhas and bodhisattvas, however, can be called immeasurable and boundless" clarifies the Mahāyāna as different from the Hīnayāna. The acceptance and understanding can be known.
