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 I can say that I have superseded most in my sadhana [practice].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. IyengarPenetration of our mind is our goal, but in the beginning to set things in motion, there is no substitute for sweat.
B.K.S. IyengarAll of us have a dormant spark of divinity in us which has to be fanned into flame by yoga.
