The practice of asanas purges the body of its impurities, bringing strength, firmness, calm, and clarity of mind.
B.K.S. IyengarYou have to create love and affection for your body, for what it can do for you. Love must be incarnated in the smallest pore of the skin, the smallest cell of the body to make them intelligent so they can collaborate with all the other ones, in the big republic of the body. This love must radiate from you to others.
B.K.S. IyengarA scientist sets out to conquer nature through knowledge - external nature, external knowledge. By these means he may split the atom and achieve external power. A yogi sets out to explore his own internal nature, to penetrate the atom (atma) of being. He does not gain dominion over wide lands and restless seas, but over his own recalcitrant flesh and febrile mind.
