Yoga is an art, a science and a philosophy. It touches the life of man at every level, physical, mental, and spiritual. It is a practical method for making one's life purposeful, useful and noble.
B.K.S. IyengarWhen you cannot hold the body still, you cannot hold the brain still. If you do not know the silence of the body, you cannot understand the silence of the mind. Action and silence have to go together. If there is action, there must also be silence. If there is silence, there can be conscious action and not just motion.
B.K.S. IyengarPenetration of our mind is our goal, but in the beginning to set things in motion, there is no substitute for sweat.
B.K.S. Iyengar
