There is one aspect of life which is known to us, our everyday life in which we are conscious of all that we do, and this aspect may be called the outer life. There is another part of our life of which we are very often unconscious and which may be called the inner life. To be without inner life is like being without an arm or a leg or an eye or an ear; but even that does not really illustrate the idea of the inner life. The reason is that the inner life is much greater and nobler and much more powerful than the outer life. Man gives great importance to the outer life, being absorbed in it from morning till evening and not being conscious of the other aspect. Thus all that matters to man is what happens to him in his outer life, and the occupations of his outer life keep him so absorbed that he has hardly a moment to think of the inner life.
