大般涅槃經義記 2.218

2.218

自下第三有難解者問答重顯。顯前令他無瘡疣義，有兩問答：初就喻為問，「世醫悉治一切瘡不？」佛答：不定。後就法為難，先牒佛語，下就設難。「若言治已，云何有未得涅槃者？若未悉得，云何上言療治此已欲至他方？」佛答：不定。先舉二人，次列其名，後就其人明治、不治。「除一闡」下簡去不治，就其所治結成涅槃無瘡疣義，從偈至此明解脫處。

From here below, third, for those [points] that are difficult to understand, question and answer clarify them again. To clarify the previous meaning of causing others to be without sores or warts, there are two questions and answers: First, inquiring in terms of the metaphor: "Does a worldly physician heal all sores or not?" The Buddha answers: it is not fixed. Next, raising an objection in terms of the Dharma, [Kāśyapa] first cites the Buddha's words, and below raises the objection based on them: "If you say they have already been healed, why are there those who have not yet attained nirvāṇa? If they have not all attained it, why did you say above, 'having healed these, he wishes to go to another region'?" The Buddha answers: it is not fixed. First he adduces two persons, next lists their names, and then in terms of those persons explains the healed and the unhealed. From "except the icchantika" below, he sets aside those not healed, and in terms of those healed concludes the meaning of nirvāṇa being without sores or warts. From the verses up to this point clarifies the locus of liberation.
