Yoga is the method by which the restless mind is calmed And the energy directed into constructive channels.
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.
B.K.S. IyengarSometimes our body is willing, but our mind is weak. Sometimes our mind is willing, but our body is weak. Do not be afraid. Strive to extend your capacity but do not be disappointed with yourself. What does not challenge us, cannot change us.
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.
