In the last few years, I’ve chosen to use the Metta Sutta, the Buddha’s sermon on impartial kindness, as my principal text. I’ve been particularly interested in teaching the Metta Sutta because I think it presents an overview of the entire practice path that the Buddha taught. It begins with the challenging and inspiring line, “This is what should be done by one who is skilled in goodness and who knows the path of peace,” and continues with instructions for morality practice, mental discipline, and the cultivation of wisdom. I love that this text is totally unequivocal. The cultivation of unshakable goodwill toward all beings, “omitting none”—a practice made possible through the “gladness and safety” that is the fruit of firm ethics—liberates the mind from “fixed views” so that its essential peace is undisturbed.
