It was foolish, stupid, and unskillful of me to act in that way. Please, sir, accept my mistake for what it is, so I can restrain myself in future.” “Indeed, sister, you made a mistake. It was foolish, stupid, and unskillful of you to act in that way. But since you have recognized your mistake for what it is, and have dealt with it properly, I accept it. For it is growth in the training of the Noble One to recognize a mistake for what it is, deal with it properly, and commit to restraint in the future.”

And what is the training of a Holy One? He teaches Dhamma that’s good in the beginning, good in the middle, and good in the end, meaningful and well-phrased. And he reveals a spiritual practice that’s entirely full and pure. This is the training of a Holy One. This is how a Holy One or a Holy One’s training remain in the world for the welfare and happiness of the people, out of sympathy for the world, for the benefit, welfare, and happiness of gods and humans.
