菩薩從兜術天降神母胎說廣普經 2.7

2.7

「吾從阿僧祇劫常修口淨，不從彼聞此說，不從此聞彼說，得廣長舌相。遍滿十方阿僧祇恒河沙剎，放舌相光明；一一光明皆有化佛，一一化佛皆坐七寶座上，以清淨音聲演說無量口行，清淨報業真實所作，成辦四事無畏，曉了諸法無來無去，音響清淨，以度生死畏地無所罣礙，分別眾生一一音響，演說無量智慧辯才，度五道淵法法成就，以九解脫而自瓔珞，十力具足，空性無形不可沮壞，其聞法者悉皆信解，是謂菩薩摩訶薩口淨舌相果報。

"Through asaṃkhyeya eons of constantly cultivating purity of speech—not hearing from that side and speaking to this side, nor hearing from this side and speaking to that side—I attained the mark of the broad and long tongue. Filling asaṃkhyeya Ganges-sands of lands across the ten directions, it emits light from the mark of the tongue; in each light there are transformation buddhas, and each transformation buddha sits upon a seven-jeweled seat, expounding with pure voice immeasurable verbal actions, true deeds of pure retribution, fulfilling the four fearlessnesses, understanding that all dharmas have neither coming nor going, pure in sound, having crossed the fearful ground of birth and death without hindrance, discerning each sound of sentient beings, expounding immeasurable wisdom and eloquence, crossing the abyss of the five destinies with dharma after dharma accomplished, adorning himself with the nine liberations, fully endowed with the ten powers, empty in nature and formless, indestructible, so that those who hear the Dharma all believe and understand. This is called the bodhisattva-mahāsattva's retribution of the mark of the tongue from purity of speech.
