是真智者。以菩提是覺，覺即智故。論云：「依此法身說名本覺，法報合說同名真身，如來說此真智之法，乃名如來為真語者。」此則以所說名能說也。餘皆例此。諦實等義已如前說。

[Regarding] 'is true wisdom': Because bodhi is awakening, and awakening is wisdom. The treatise says: 'Relying on this dharmakāya, it is called original awakening; speaking of the dharma[-kāya] and saṃbhoga[-kāya] together, they are collectively called the true body. The Tathāgata's speaking of this dharma of true wisdom is why the Tathāgata is called "one who speaks the truth."' This names the speaker by what is spoken. The rest are all analogous to this. The meanings of 'truth', 'reality', and so forth are as explained before.
