The battle of yoga is with the body and with the ego. You must conquer your ego, or small self, so that you can let your soul, your big Self, be victorious.
B.K.S. IyengarLook after the root of the tree, and the fragrant flower and luscious fruits will grow by themselves. Look after the health of the body, and the fragrance of the mind and richness of the spirit will follow.
B.K.S. IyengarThink light! Try to impart a feeling of lightness to the body. Think light. This can be achieved by mentally extending yourself outwards from the centre of the body, i.e., think tall. Think not just of raising your arms but of extending them outwards and when you are holding them still, think again of reaching still further away from your body. Do not think of yourself as a small compressed suffering thing. Think of yourself as graceful and expanding - no matter how unlikely it may seem at the time.
