“‘Gentlemen, the Tathāgata’s words and actions correspond. He does what he says, and he says what he does. Thus, he has achieved one teaching and the next. I’ve not seen a Tathāgata, Arhat, and Completely Awakened One in the past, future, or present whose words and actions correspond and achieve one teaching and the next like the Buddha.
