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 I can say that I have superseded most in my sadhana [practice].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. IyengarWhen the asana is correct, there is lightness, a freedom. Freedom comes when every part of the body is active. Let us be free in whatever posture we are doing. Let us be full in whatever we do.
B.K.S. Iyengar
