華嚴經明法品內立三寶章 2.11

2.11

初中有二：一、謂如來能以一音演說一切差別之法，所謂貪欲多者，即聞如來說不淨觀，如是等乃至一切，故名圓音。是故《華嚴》云「如來於一語言中，演說無邊契經海。」二、謂如來一音能同一切差別言音，謂諸眾生各聞如來唯己語，故《華嚴經》云「一切眾生語言法，一言演說盡無餘。」

In the first [gate] there are two: (1) It means that the Tathāgata can expound all distinct phenomena with a single voice: namely, those with much lust hear the Tathāgata expound the contemplation of impurity, and so on up to all things; therefore it is called the round voice. Hence the Avataṃsaka says: "The Tathāgata within a single speech expounds a boundless ocean of sūtras." (2) It means that the single voice of the Tathāgata can identify with all distinct sounds of speech; that is, the various sentient beings each hear the Tathāgata speaking only their own language. Hence the Avataṃsaka Sūtra says: "The linguistic conventions of all sentient beings / Are expounded in a single word without remainder."
