I don't stretch my body as if it is an object. I do yoga from the self towards the body, not the other way around.
B.K.S. IyengarWhile doing the postures, your mind should be in half-consciousn ess, which does not mean sleep. It means silence, emptiness, space, which can then be filled with an acute awareness of the sensations given by the posture. You watch yourself from inside. It is a full silence.
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.
