Extension brings space, space brings freedom, freedom brings precision. Precision is truth.
B.K.S. IyengarYoga is about the will, working with intelligence and self-reflexive consciousness, can free us from the inevitability of the wavering mind and outwardly directed senses.
B.K.S. IyengarYou must do the asana with your soul. How can you do an asana with your soul? We can only do it with the organ of the body that is closest to the soul - the heart. So a virtuous asana is done from the heart and not from the head. Then you are not just doing it, but you are in it. Many people try to think their way into an asana, but you must instead feel your way into it through love and devotion
