Backbends are not poses meant for expressionism. Backbends are meant to understand the back parts of our bodies. The front body can be seen with the eyes, but the back body can only be felt. That's why I say these are the most advanced postures, where the mind begins to look at the back.
B.K.S. IyengarYou must be as joyful when you fail again and again as you are joyful when you succeed. It is often when you fail that you move toward the goal without being aware of it. You must feel joy even when you have not fully succeeded but only moved toward achievement of your goal.
B.K.S. IyengarThe best way to overcome fear is to face with equanimity the situation of which one is afraid.
B.K.S. IyengarAs a breeze ruffles the surface of a lake and distorts the images reflected therein, so also the chitta vrtti (fluctuations of mind) disturb the peace of the mind. The still waters of a lake reflect the beauty around it. When the mind is still, the beauty of the Self is seen reflected in it.
B.K.S. Iyengar
