You can't forgive without loving. And I don't mean sentimentality. I don't mean mush. I mean having enough courage to stand up and say, 'I forgive. I'm finished with it.'
But reason always cuts a poor figure beside sentiment; the one being essentially restricted, like everything that is positive, while the other is infinite.
Since we desire the true happiness that is brought about by a calm mind, and such peace of mind arises only from having a compassionate attitude, we need to make a concerted effort to develop compassion.
