You have to get rid of borders, limits, and classifications; then light comes. We see everything on the screen of our ideas. We must get rid of that screen to be able to see what is behind. X's ideas are limited, that is why he remains on the surface. Y got rid of the limits, so she always goes to the depths. We should always meet people and new subjects with no set frame of mind. We have to live like that even after long acquaintance. We must get rid of every set idea to approach everything and everyone with love.
B.K.S. IyengarYes, flexibility of body and physical perfection for Yogasana is important. However more important is the state of your mind, Meditative mind. Your flexibility might be excellent but if your mind is not attentive, you are merely doing some physical exercise, not Yoga.
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 I can say that I have superseded most in my sadhana [practice].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.
