Abhyasa (practice) is a dedicated, unswerving, constant, and vigilant search into a chosen subject pursued against all odds in the face of repeated failures, for indefinitely long periods of time.
B.K.S. IyengarYes, flexibility of body and physical perfection for Yogasana is important. However more important is the state of your mind, Meditative mind. Your flexibility might be excellent but if your mind is not attentive, you are merely doing some physical exercise, not Yoga.
B.K.S. IyengarOne day you too may experience what I have experienced. So right away go and practise.
B.K.S. IyengarAs long as you do not feel the serenity in the body, in each and every joint, there is no chance for emancipation. You are in bondage. So while you are sweating and aching, let your heart be light and let it fill your body with gladness. You are not only becoming free, but you are also being free. What is not to be glad about? The pain is temporary. The freedom is permanent.
B.K.S. Iyengar
