說無垢稱經疏 2.32

2.32

贊曰：上二句，顯處眾說法無畏功德。下兩句，顯演法音聲深大功德。由諸煩惱不染、無明皆已不行，亦無分別我他勝於己，處眾說法，不見有能過自身者，是故無畏如師子吼。講說談論，其聲若雷，隱振隱振，深而大故。前五音中，此第一也。

Commentary: The upper two phrases reveal the virtue of expounding the Dharma in the assembly without fear. The lower two phrases reveal the virtue of the voice expounding the Dharma being profound and vast. Because they are untainted by any defilements, ignorance has ceased to operate, and they do not discriminate whether self or other is superior to oneself, when expounding the Dharma in the assembly they do not see anyone who can surpass themselves; therefore, they are fearless like a lion's roar. In lecturing and discussing, their voice is like thunder, reverberating and rumbling, deep and grand. Among the five voices mentioned before, this is the first.
