金剛般若經旨贊 2.30

2.30

經。世尊至說名實相　贊曰。此拂情想也言實相者無相為相。為令離於虛妄執故。非謂即有此實相也。若離虛妄契乎無相。是故佛說為實相耳。既於此經詮實相理。餘經未說。不同餘經。即頌七義中亦不同餘法。

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".
