When you are practicing, do not just do that for the sake of doing. Learn to reflect while you are practising. Make your mind and brain observe and relearn what you are doing. Doing is mechanical; learning is dynamic.
B.K.S. IyengarAs each individual is electrically alive and dynamic, so yoga is a living, dynamic force in life. In order to savor its essence, one needs a religiously attentive dynamic practice done with awareness and absorption.
B.K.S. IyengarI think overall the majority of people who are practicing it as a subject are following the right line. For the aberration, don't blame yoga or the whole community of yogis
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 I can say that I have superseded most in my sadhana [practice].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 challenge of yoga is to go beyond our limits - within reason. We continually expand the frame of the mind by using the canvas of the body. It is as if you were to stretch a canvas more and create a larger surface for a painting. But we must respect the present form of our body. If you pull too much at once, we will rip the canvas. If the practice of today damages the practice of tomorrow, it is not correct practice.
