B.K.S. IyengarChange leads to disappointment if it is not sustained. Transformation is sustained change, and it is achieved through practice.
B.K.S. IyengarI also say with backbends, you have to be cautiously bold. Not carelessly bold. You have to descend to the dictation of the spine. You cannot command from the brain to do the poses. As you play with a child, guarding the child from injuries, similarly you have to play in backbends, guarding your spine.
