3.30

經曰「梵聲猶雷震」至「今說仁諦聽」者，述云：此第四、如來酬請。有二：此初、略標許勅也。梵聲者總舉，八音者別歎，如《梵摩喻經》中說：一最好聲聲哀妙故、二易了聲言辨了故、三調和聲大小得中故、四柔煗聲聲濡輕故、五不誤聲言無錯失故、六不女聲聲雄朗故、七尊慧聲言有威肅故、八深遠聲聲遠故。以此妙音酬觀音，故云暢妙響。

On the sūtra's words from "A Brahmā voice like rolling thunder" to "I now explain; listen attentively, noble one," the Commentary states: This fourth [part] is the Tathāgata responding to the request. It has two parts: this first briefly indicates the granting of the request. "Brahmā voice" is a general designation; the eight tones are a specific praise. As stated in the Brahmāyu-sūtra: first, the best voice, because the sound is sorrowfully sublime; second, the easily understood voice, because the words are clearly enunciated; third, the harmonised voice, because the volume is balanced; fourth, the gentle and soft voice, because the sound is light and supple; fifth, the unerring voice, because the words have no mistakes; sixth, the non-feminine voice, because the sound is heroic and clear; seventh, the dignified and wise voice, because the words command awe and gravity; eighth, the profound and far-reaching voice, because the sound travels far. Responding to Avalokiteśvara with these wondrous voices, it therefore says "gives forth a wondrous utterance."
