You can actually bring these emotions to any part of the body, and train to adjust the intensity and clarity of these emotions. There's one bit about the happiness: it might be mostly in one's head, but it covers the whole body. Happiness is related to contentedness, that feeling that you don't need to go anywhere and you're good right here. If happiness did not cover a part of the body, then usually, that part will start agitating for attention. You are no longer content.
