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 I can say that I have superseded most in my sadhana [practice].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. IyengarAs we explore the soul, it is important to remember that this exploration will take place within nature (the body), for that is where and what we are.
B.K.S. IyengarWe often fool ourselves that we are concentrating because we fix our attention on wavering objects.
