The cure to combat the three Ss- stress, strain, and speed- can be found in three Ws- the work of devoted practice, the wisdom that comes of understanding the self and the world, and worship because ultimately surrendering to what we cannot control allows the ego to relax and lose the anxiety of its own infinitesimally small self in the infinitude of the divine.
B.K.S. IyengarYou must fill every inch of your body with the asana from your chest and arms and legs to the tips of your fingers and toes so that the asana radiates from the core of your body and fills the entire diameter and circumference of your limbs. You must feel your intelligence, your awareness, and your consciousness in every inch of your body.

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 I can say that I have superseded most in my sadhana [practice].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.
