金剛般若經旨贊 2.30

2.30

Sūtra: World-Honoured One, [...] is called the true mark. / Commentary: This sweeps away feelings and thoughts. What is called the true mark takes marklessness as its mark; it is for the purpose of abandoning false graspings, not meaning that there is this actual true mark. If one abandons false [discriminations] and accords with marklessness, therefore the Buddha merely speaks of it as the true mark. Since this sūtra expounds the principle of the true mark, which other sūtras have not yet spoken, it is unlike other sūtras; this corresponds in the verse to the one among the seven meanings: "And is also unlike other dharmas".
