" Love and hate: they live and tumble together in every heart, like wolf cubs tussling in a cave. There is no killing the wolf of hate; the aversion in such an attempt would actually create what you’re trying to destroy. But you can watch that wolf carefully, keep it tethered, and limit its alarm, righteousness, grievances, resentments, contempt, and prejudice. Meanwhile, keep nourishing and encouraging the wolf of love. "
