There is a famous meditation master from Vietnam, Thich Nhat Hanh, who emphasises very much that when you are sitting. just to smile while sitting. He says that when you have a Buddha-like smile the face can relax and the meditation can be relaxed, there can be a lightness to the practice. And he also emphasises very much the need to smile at others. The only thing is that it must come naturally.
