贊曰：第五問答。空理義云：我與涅槃，勝義諦中二俱平等，由彼二性空無體故。應理義云：遍計所執，我與涅槃二俱平等，妄心所執性皆空故，非真涅槃。又體非有，與妄所執我相同無，涅槃非是妄所執故。若真涅槃亦妄所執，諸聖等趣？何所證也？又所執有，可異涅槃，而稱不等。所執既無，不異涅槃，是故平等。

The Commentary says: The fifth question and answer. The perspective of the Principle of Emptiness (Mādhyamika) states: In the ultimate truth, both the self and Nirvāṇa are equal, because their two natures are empty and devoid of substance. The perspective of the Principle of Reason (Yogācāra) states: The imagined self and Nirvāṇa are both equal, because the natures clung to by the deluded mind are both empty, not being true Nirvāṇa. Furthermore, their substances are non-existent, sharing the same non-existence as the falsely clung self, because Nirvāṇa is not that which is falsely clung to. If true Nirvāṇa were also that which is falsely clung to, toward what would all the noble ones proceed, and what would they realize? Furthermore, if that which is clung to were existent, it could be distinct from Nirvāṇa and called unequal; since that which is clung to is non-existent, it is not distinct from Nirvāṇa, and is therefore equal.
