大般涅槃經義記 6.126

6.126

自下第二解前經中世間不知，菩薩能知異世間義。迦葉先問，「如佛所說一切世間不知、見、覺，菩薩能者」牒佛昔言。下就此言進退兩徵，初問菩薩若是世間，不應說言世間不知，菩薩能知。後問菩薩若非世間，有何等異？

From here below is the second [part], explaining the meaning in the previous sūtra that while the world does not know, the bodhisattva is able to know, which is different from the world. Kāśyapa first inquires: "As the Buddha stated, all the world does not know, see, or perceive, but the bodhisattva is able to" cites the Buddha's past words. Below, based on these words, he interrogates both alternatives: First, he asks, if the bodhisattva belongs to the world, one should not say that the world does not know while the bodhisattva can know. Next, he asks, if the bodhisattva does not belong to the world, what kind of difference is there?
