金剛般若經贊述 2.39

2.39

無著云，此何所顯示？欲令信如來故能忍。於中真語者，為顯世諦相故。實語者，為顯世諦修行有煩惱及清淨相故；於中實者，此行煩惱、此行清淨故。如語者，為第一義諦相故。不異語者，為第一義諦修行有煩惱及清淨相故，說此真語也。此意總云，如來三界獨尊，天人師，既為法界主，作五趣醫，脫屣在家之上飾，棄捨輪王之大祚，道成正覺，所欲皆成，既不規名利，復不求安樂，何忽有妄語乎？

Asaṅga says: What does this demonstrate? It is intended to cause them to have faith in the Tathāgata so that they can endure. Herein, "speaker of truth" is to reveal the lakṣaṇa of saṃvṛtisatya. "Speaker of reality" is to reveal that the cultivation of saṃvṛtisatya has lakṣaṇas of defilement and purification; within that, what is real is that this practice is defilement and this practice is purification. "Speaker of suchness" is for the sake of the lakṣaṇa of paramārthasatya. "Speaker of non-alteration" is because cultivation in paramārthasatya has lakṣaṇas of defilement and purification, that he speaks this truth. The general meaning here is: The Tathāgata is the sole honored one in the three realms, the teacher of devas and humans; since he is the master of the dharmadhātu and acts as the physician for the five destinies, having cast off the supreme ornaments of the householder like discarded sandals, and abandoned the great throne of a cakravartin, his Way attained complete awakening and whatever he wished was accomplished. Since he neither aims for fame and gain, nor seeks comfort and pleasure, why would he suddenly utter false speech?
