經。世尊是實相者則是非相是故如來說名實相　第二釋成也。言實相者。謂依此經生如實信。即是非相者。謂不同世間虛妄信也。是故如來說名實相者。引教證成結初句也。

Sūtra: Bhagavat, this real mark is precisely a non-characteristic; for this reason, the Tathāgata speaks of it as the real mark. Second, this is the explanation and completion. As for 'the real mark', it refers to generating faith in accordance with reality based on this sūtra. 'Precisely a non-characteristic' means that it is not like the false and deluded faith of the worldly. 'For this reason, the Tathāgata speaks of it as the real mark' quotes the teaching to corroborate and conclude the opening sentence.
