7.265

就後破空顯實門中，「云何為知，知無有我、無有我所」是知無也，「知諸眾生皆有性」下是知有也，「知生有性」正明知有，「以佛性」下約果顯有，「如此皆」下就人辯異。「以是」下結，准驗斯文，以空為窮，判知不了。

In the latter approach of refuting emptiness to reveal the real: "How is it knowing? Knowing there is no self and no what belongs to self" is knowing nonexistence; the passage from "knowing that all sentient beings have the nature..." onward is knowing existence; "knowing that sentient beings have the nature" directly clarifies knowing existence; the passage from "Because of the buddha-nature" onward reveals existence with reference to the fruit; the passage from "All these..." onward discerns differences with reference to persons; the passage from "For this reason" onward concludes: examining this text, one judges and knows that taking emptiness as the ultimate is inexhaustive.
