Today there seems to be a great seeking and enthusiasm everywhere; a new kind of urge seems to be aroused in humanity to understand life and truth. A very large number of people are looking for the best way of gaining the power needed to battle through life; and a small number again are looking for some way of bringing peace to themselves and to others. But both of these in their pursuit lack that balance which can only be brought about by understanding, by studying, and by practicing the knowledge of war and peace together. Without knowing about war one cannot thoroughly know about peace; without understanding peace one cannot thoroughly know about war. What is necessary at the present time is the study of life in general, and that means the knowledge of such questions as what is the purpose of life, what is really beneficial, what is nature, and where is the goal. It is no use practicing something before studying it. What does worldly wise mean? It means expert in this warfare of life; to know how to battle, how to make peace, why to battle, and what aim is accomplished by peace.
