大般涅槃經義記 1.140

1.140

下佛答之。「爾時世尊」，舉酬答人。「一切種智無上調御」，舉酬答德。於一切法種別而知名一切智，自調、調他，調御中極名無上調御。別即種智是能說德，無上調御是受供德，自調心故，能受物養。通則義等，一切智故，能為說法、能受其供，并知說時及與受時；無上調故，能調眾生，為之說法、為之受供。「告純陀」下明酬答詞，先總歎善所請事好，是故言善。哉是助詞，由請契當，重言以歎。

Below, the Buddha answers him. 'At that time the World-Honoured One' cites the person who replies. 'Omniscient, supreme tamer' cites the virtues of the one who replies. Knowing all dharmas distinctively according to their kinds is called omniscience; taming oneself and taming others, the pinnacle among tamers, is called the supreme tamer. Distinctly: omniscience is the virtue of being able to preach; supreme tamer is the virtue of accepting offerings; because his own mind is tamed, he can accept the sustenance of beings. Generally: their meanings are equal: because of omniscience, he can preach the Dharma and accept his offering, and he also knows the time to preach and the time to accept; because he is the supreme tamer, he can tame sentient beings, preaching the Dharma for them and accepting their offerings. From 'addressed Cunda' onward clarifies the words of the reply. First, he generally praises him as 'good': what was requested is fine, therefore he says 'good'. 'Indeed' (zai) is a particle; because the request was fitting, he repeats the word to praise him.
