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 I can say that I have superseded most in my sadhana [practice].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. IyengarFor me there were only two ways on the precipice - either I have to fall in or I have to fall out, to accept or say good-bye. The moment I crossed the precipice, it no longer was a discipline - it became a passion, an urge to pursue. Then I experienced freedom. Freedom comes when the discipline revolutionizes the discipline as a passion for the art.
B.K.S. IyengarThe sleeping tortoise takes all its limbs into its carapace. So does the yogi: going back into himself he does not see anything worldly any longer, he makes peace in himself.
