As a breeze ruffles the surface of a lake and distorts the images reflected therein, so also the chitta vrtti (fluctuations of mind) disturb the peace of the mind. The still waters of a lake reflect the beauty around it. When the mind is still, the beauty of the Self is seen reflected in it.
B.K.S. IyengarRegarding 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 I can say that I have superseded most in my sadhana [practice].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. IyengarThe union of nature and soul removes the veil of ignorance that covers our intelligence.
