Note that your posture affects your mood and energy in the same way that your mood affects your posture. If the face is relaxed it is easier to relax within and if the spine is bent forward and the shoulders fall it is hard to see the heavens and see the birds overhead. Pay attention to other people as well as we mirror our surroundings and in many times become happy or sad just to be like the person close to us. Pay attention and it will set you free.
