說無垢稱經疏 4.428

4.428

贊曰：此能說真，言合理故。清淨法界，萬德莊嚴，無相為相，故言一相。諸經中說：一切諸法，皆同一相，所謂無相而為相故。能於法界一相法中，說無邊相莊嚴清淨法界法門，謂說佛性、如來藏、法身、真如、涅槃、解脫、法界、法性等無量法門。說眾多德相莊嚴於一相，言雖多相仍契一相，故名能說。

Commentary: This is being able to expound the ultimate, because his words accord with reason. The pure dharmadhātu is adorned with myriad virtues; taking the signless as its characteristic, it is therefore called "the single characteristic." It is said across the sūtras: "All dharmas share the single characteristic, namely taking signlessness as their characteristic." Being able, within the single characteristic dharma of the dharmadhātu, to expound the dharmaparyāya of the pure dharmadhātu adorned with boundless characteristics, means speaking of the Buddha-nature, the tathāgatagarbha, the dharmakāya, tathatā, Nirvāṇa, vimokṣa, dharmadhātu, dharmatā, and other such immeasurable dharmaparyāyas. Expounding numerous virtuous characteristics to adorn the single characteristic, though spoken of as many characteristics, still accords with the single characteristic; hence it is called "able to expound."
