This exercise is done standing. Tune into how your posture is initially and what emotions and sensations accompay that posture. Permit yourself some time to explore the posture to find the meaning in this. Posture is often taken as a given and we don't realize that our emotional life is very connected with how we are inhabiting our posture.
