Evil-doers who denounce the wise resemble a person who spits against the sky; the spittle will never reach the sky, but comes down on himself. Evil-doers again resemble a man who stirs the dust against the wind; the dust is never raised without doing him injury.

If for just the time of a finger-snap a monk produces a thought of loving-kindness, develops it, gives attention to it, such a one is rightly called a monk. Not in vain does he meditate. He acts in accordance with the master's teaching, he follows his advice. How much more so if he cultivates it.
I will purify my bodily actions through repeated reflection. I will purify my verbal actions through repeated reflection. I will purify my mental actions through repeated reflection. That's how you should train yourself.
