I shall give an example of a person facing a struggle: a person who has a disagreeable conversation, who has an inclination to retort. At the same time this person has no battle with this, of giving back. By letting his force go out, by insulting back, he has lost his power. By controlling this inclination, one has a thousandfold greater power. For the moment that it happens, to humiliate oneself, to crush one's pride, to crush oneself, one feels crushed both sides, by not answering and then by crushing oneself. "I have given back too" gives a little pride, a satisfaction.
