In plain words
He had given Pṛthvīrāj's own sister to him in marriage. Making friends with such a man, this Muhammad Ghori came attacking him again. But because he came unexpectedly, Pṛthvīrāj was caught in Muhammad Ghori's hands. He was caught, after all. Could he not have forgiven him even once? Turning merciless and hard, he put out his eyes. Do you see? How much harm he did to the one who had done him so much good! So doing good must not go this way. Though you forgive once or twice, when it goes beyond limit you must not set about forgiving. That will turn into danger for you yourselves. So hold good feelings towards all. But with regard to certain times and occasions, we must move very carefully. We must arrange our words as calmly, as sweetly, as lovingly as we can. Not for anyone else's satisfaction. We must arrange them for our own satisfaction.
We get angry. Some kinds of turmoil go on in the heart. We must make the right effort to master it properly and to calm it. Because anger has come, we must not put it into action at once.
For one who has anger, no work bears fruit, harms come; doing sinful deeds, he ends up being told 'Shame, go away!', be sure.
Not only this:
it ruins his wealth, it burns up the honour he has, it estranges his own people; for people, through anger, everything is spoiled.
When anger comes, there are little tricks for cooling it. Students! The moment you get angry, leave that place. That is the very first thing to do. Go inside, take a mirror, and look at your face. Then you yourself feel disgust. It looks ugly. It looks like Śūrpaṇakhā. So you get angry at your anger. You must think: 'Shame, anger must never come.' If the anger has not gone down by then, go to the bathroom. Turn the tap.
