Regarding perfection, that's a very difficult question. I can say that I have superseded most in my sadhana [practice]. I am in it, and my mind and my intelligence gets better in my sadhana, and it reaches a certain place. When I stretch, I stretch in such a way that my awareness moves, and a gate of awareness finally opens... My body is a laboratory, you can say. 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. IyengarFeeling the movement of movements is wandering to the past or future. Living in the movements of movement is being in the present.
B.K.S. IyengarFaith, courage, and intelligent and uninterrupted awareness - these qualities are to be present whether one is wide awake, half asleep, or in deep slumber. An individual who lives like this performs his daily actions with a mind free from selfishness. This is poise in action. And this poise leads to that serenity which is in the truest sense a healthy mind in a healthy body.
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.
