大般涅槃經集解 64.56

64.56

案僧亮曰：以比丘執定我為問，故答無定我也。比丘三問，皆是執著，一問名、二問實、三問緣。是以如來遮其實計，故云無我我所也。

Sengliang comments: Because the monk posed his question while clinging to a fixed self, the answer was that there is no fixed self. The monk's three questions were all attachments: the first asked about the name, the second asked about the reality, and the third asked about the conditions. Therefore the Tathāgata negated his reckoning of reality, saying there is no self or what belongs to a self.
