You 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. IyengarIntellectuals tend to be arrogant. Intelligence, like money, is a good servant but a bad master. When practicing pranayama, the yogi [makes] himself humble and without pride in his intellectual attainments.
