When an asana is done correctly the body movements are smooth, there is lightness in the body and freedom in the mind.
B.K.S. IyengarIt is through the alignment of the body that I discovered the alignment of my mind, self, and intelligence.
B.K.S. IyengarWhen you are practicing, do not just do that for the sake of doing. Learn to reflect while you are practising. Make your mind and brain observe and relearn what you are doing. Doing is mechanical; learning is dynamic.
