說無垢稱經疏 2.28

2.28

贊曰：說法音聲勝妙功德。說法聲韻如頻迦音，於一切眾生聲中第一。微者密也，善說深義。妙者好也，哀雅可愛。佛有五種美妙音聲，一、甚深如雷；二、清徹遠聞，聞者悅樂；三、入心敬愛；四、諦了而解；五聽者無厭。此具後四，故說言音微妙第一。即是三十二中梵音聲相，功德最大，如經校量。

Commentary: This is the supreme and wondrous virtue of the voice expounding the Dharma. The tone and cadence of expounding the Dharma are like the voice of a kalaviṅka, supreme among the voices of all sentient beings. 'Subtle' (wei) means profound and concealed, skillfully expounding deep meanings. 'Wondrous' (miao) means excellent, graceful, elegant, and pleasing. The Buddha has five kinds of beautiful and wondrous voices: first, extremely deep like thunder; second, clear and resonant heard from afar, bringing joy to hearers; third, entering the heart with reverence and love; fourth, understood with certainty; fifth, hearers never tire of it. These bodhisattvas possess the latter four, hence it says their speech and voice are wondrous and supreme. This is precisely the mark of the Brahmā voice among the thirty-two marks, of the greatest merit, as weighed and compared in the sūtras.
