The Yogi conquers the body by the practice of asanas, making the body a fit vehicle for the spirit. The Yogi knows that it is a necessary vehicle for the spirit, for a soul without a body is like a bird deprived of its power to fly.
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.
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.
As a well cut diamond has many facets, each reflecting a different color of light, so does the word yoga, each facet reflecting a different shade of meaning and revealing different aspects of the entire range of human endeavor to win inner peace and happiness.
