大般涅槃經義記 1.177

1.177

下兩偈中，初偈述上第四偈中「汝若不請，我命不全」，是諸眾生啼泣面腫，明現悲苦，身命不全。「悉為生死苦水所漂」，明沒生死，慧命不全。後偈述上是故應見為啟請調御師。「以是故」者，以眾啼泣，生死漂故。「應長信」者，對前啼泣，請佛住也。眾謂佛滅，所以啼泣，佛應久住，長其常信。「為斷生死」，對前生死苦水所漂，請佛斷也。「久住於世」，總以結請。

Within the two verses below, the first verse recounts "if you do not entreat him, our lives will not be intact" in the fourth verse above; these sentient beings weep until their faces are swollen, explaining their present grief and suffering and that their physical lives are not intact. "All drifted away by the bitter waters of birth and death" explains their sinking into birth and death, and that their life of wisdom is not intact. The latter verse recounts "therefore you should go to entreat the Tamer on our behalf" above. "For this reason" means because the multitude weeps and is drifted away by birth and death. "Should foster constant faith" means, in response to the preceding weeping, entreating the Buddha to abide. The assembly thinks the Buddha will be extinguished, which is why they weep; the Buddha should abide long to foster their constant faith. "In order to sever birth and death" means, in response to being drifted away by the bitter waters of birth and death earlier, entreating the Buddha to sever it. "Abiding long in the world" summarizes and concludes the entreaty.
