The 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.
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. IyengarYoga takes us to an unconditioned freedom, because yoga sees even good habits as a form of conditioning or limitation.
B.K.S. IyengarYoga is meant for the purification of body and its exploration as well as for the refinement of the mind.
B.K.S. IyengarAs long as the body is not in perfect health, you think about it, and that prevents you from thinking of the mind. The sound mind is a sound body.
