Give yourself a few seconds to feel relaxed. Then smile from your heart. Don’t worry how you do it; just do it. Just smile from your heart and feel, really feel, how relaxed, cheerful and happy you are. It is a big mistake to think I am being farcical. But I can tell you, in my capacity as a chi kung grandmaster, that this feeling of relaxation and cheerfulness from your heart may possibly be the best benefit of this exercise.
