Yoga is an interior penetration leading to integration of being, senses, breath, mind, intelligence, consciousness, and Self. It is definitely an inward journey, evolution through involution, toward the Soul, which in turn desires to emerge and embrace you in its glory.
B.K.S. IyengarThe beauty of a lake reflects the beauty around it. When the mind is still, the beauty of the Self is seen reflected in it.
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.
