When 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.
Willpower is concrete, not ethereal. When you do something, you demonstrate your willpower, and it becomes all the easier to have the same power of will the next time.
Is it necessary to practice all these asanas, further and further? Is it necessary to develop scientific researches further and further? To a yogi, the body is a laboratory, a field of experiments and perpetual researches.
