You have to create love and affection for your body, for what it can do for you. Love must be incarnated in the smallest pore of the skin, the smallest cell of the body to make them intelligent so they can collaborate with all the other ones, in the big republic of the body. This love must radiate from you to others.
B.K.S. IyengarAsanas maintain the strength and health of the body, without which little progress can be made. Asanas keep the body in harmony with nature
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. 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 I can say that I have superseded most in my sadhana [practice].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.
