A stable mind is like the hub of a wheel. The world may spin around you, but the mind is steady.
B.K.S. IyengarYoga cultivates the ways of maintaining a balanced attitude in day-to-day life and endows skill in the performance of one's actions.
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.
