If someone has something that we want, say, a bigger house, we can consciously take joy in their good fortune by telling ourselves: “Good for him. Just like me, he, too, wants to be happy. He, too, wants to be successful. He, too, wants to support his family. May he be happy. I congratulate him and want him to have more success.” Mudita recognizes that life is not a zero-sum game, that there is not just one slice of cake in which someone else’s taking more means we get less. Mudita sees joy as limitless.
