大般涅槃經義記 9.258

9.258

自下第四重誡捨著。「若解如是四句義者，不應難言定有定無」正勸捨著。「若言眾生悉有性」下，舉佛獨知，遮其偏著。「如來如是隨自意」下，牒佛獨知，呵其偏著。備前四義，「眾生云何一向作解」。廣中有二：一就人明性；二「是七人不修身戒心慧」已下，誡勸捨著。前中有三：一舉喻相約之顯法；二「如恒河中七種眾生不離水」下，辨其喻意約之顯法；三「迦葉言若有因則有果」下，於前義中有難解者問答重顯。

From here below is the fourth [part], reiterating the admonition to abandon attachment. "If one understands the meaning of these four propositions, one should not object that it is definitely present or definitely absent" directly encourages abandoning attachment. "If one says that sentient beings all have the nature..." and so forth cites the Buddha's exclusive knowledge to block their one-sided attachment. "The Tathāgata in this way speaks according to his own intention..." and so forth takes up the Buddha's exclusive knowledge to reprove their one-sided attachment. When these four meanings are fully present, "how could sentient beings adopt a single-sided interpretation?" In the extensive explanation there are two [sections]: first, explaining the nature with reference to persons; second, from "these seven persons do not cultivate the body, moral discipline, mind, or wisdom" onward, admonishing and encouraging the abandonment of attachment. In the first there are three [subsections]: first, adducing the characteristics of the simile to reveal the Dharma according to them; second, from "just as the seven kinds of sentient beings in the Ganges River do not leave the water" onward, analyzing the purport of the simile to reveal the Dharma according to it; third, from "Kāśyapa said: If there is a cause, then there is a fruit" onward, asking and answering again regarding difficult points among the preceding meanings to clarify them further.
