大般涅槃經義記 5.144

5.144

就前問中，迦葉先舉如來昔言，「昔佛一時在恒河岸尸首林中」舉佛所在，「取其樹葉」舉佛所作，「告比丘」等舉佛所問，「比丘言」等舉昔所答，「我所覺」等舉昔所辯，我所覺法如大地草，所宣說者如手中葉。下就為問，「世尊爾時說如是言：如來所了無量諸法」牒佛前言，「若入四諦則為已說，若不入者應有五諦」進退徵問。下佛先歎，後為辯釋如是諸法悉在四諦。

In the first question, Kāśyapa first cites what the Tathāgata said in the past. "Formerly, the Buddha was at one time on the bank of the Ganges in a forest of corpses" cites the Buddha's location; "took some tree leaves" cites the Buddha's action; "addressed the monks," and so forth, cites the Buddha's question; "The monks said," and so forth, cites the past answer; "What I have realized," and so forth, cites what was explained in the past: the dharmas I have realized are like the grass on the great earth, while those I have proclaimed are like the leaves in my hand. Below he questions accordingly: "At that time the World-Honoured One spoke such words: The immeasurable dharmas understood by the Tathāgata—" repeating the Buddha's former words; "if they enter the four truths, then they have already been spoken; if they do not enter, there should be five truths," challenging with an either-or dilemma. Below, the Buddha first praises him, and then explains that these dharmas are all within the four truths.
