“When an asana (pose) is done correctly, the body movements are smooth, and there is lighhtness in the body and freedom in the mind. When an asana is felt as being heavy, it is wrong. You must try to impart a feeling of lightness throughout your body. This can be achieved by mentally extending yourself outward from the centre of your body, that is, think tall and act tall.” – B.K.S Iyengar
