又,舍利子!菩薩實語有四種功德。云何為四?
一者、口中常出青蓮華香。
二者、語業清淨言辭無礙。
三者、人天之中以為準繩。
四者、攝取諸佛圓滿音聲。
舍利子!菩薩實語,獲得如是四種功德。
“Śāriputra, there are four benefits for bodhisattvas who speak truthfully. What are these four? The scent of blue lotuses comes forth from their mouths; their physical, verbal, and mental actions become pure; they are taken as genuine by the world and its gods, and their words are free from confusion; and they master perfect buddha speech. Śāriputra, these are the four benefits for bodhisattvas who speak truthfully.
