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. IyengarKeep your attention internal, not external, not worrying about what others see, but what the Self sees.
B.K.S. IyengarYoga is the rule book for playing the game of Life, but in this game no one needs to lose. It is tough, and you need to train hard. It requires the willingness to think for yourself, to observe and correct, and to surmount occasional setbacks. It demands honesty, sustained application, and above all love in your heart.
