法苑珠林 32.9

32.9

又華嚴經云。一切諸佛悉有八種微妙音聲。一一音聲悉有五百妙音聲眷屬。不可稱數百千音聲以為莊嚴。無量無邊妙音聲伎樂皆悉清淨。普能演說一切諸佛正法義味。悉離恐悑安住無畏大師子吼。悉令一切法界一切眾生聞其音聲隨其本行種種善根皆令開解。是為一切諸佛最勝無上口業莊嚴。

Furthermore, the Avataṃsaka Sūtra states: "All Buddhas possess eight kinds of subtle and wonderful voices. Each voice is accompanied by five hundred retinues of wonderful voices, adorned with incalculable hundreds of thousands of voices. Limitless and boundless wonderful musical voices are all pure, universally capable of expounding the taste of the meaning of the true Dharma of all Buddhas. They are entirely free from fear, dwelling securely in the fearless, great lion's roar, causing all sentient beings throughout the entire dharmadhātu, upon hearing their voices, to attain opening and awakening in accordance with their original practices and various roots of goodness. This is the supreme and unexcelled adornment of the bodily karma of speech of all Buddhas."
