But those who have never lived in this "world" of fiery ambitions and throbbing powers, who have never been stirred by the keen, satisfying joys that go with these extraordinary, vital qualities, may ask if these invaluable powers can be developed. Are these stirring, vital forces the possession of favored classes only, or may they be obtained by anyone and everyone? In other words, can they be cultivated or developed? My reply, in nearly all cases, would be in the affirmative. There may be exceptions. There is a limit to the development of the physical force, but health is attainable by the majority.

CHAPTER II: Functional Activity-The Secret of Power Vitality means normal functioning. When the organs of the body are all performing their duties satisfactorily, you can practically be sure of a plentiful supply of vitality. So it can truly be said that proper functioning is the secret of power. The most important of all functional processes begins in the stomach. There is where the blood-making process commences, and, since a man is what the blood makes of him, you can realize the tremendous importance of this particular function. If the digestion is carried on properly, and the blood is made rich in those elements that add to life, health and strength, then the functions of the stomach are being properly performed. Strength of this organ, therefore, is absolutely indispensable in vitality building.
