The question is, how are we to be sure that there is an inner life, what proof is there? And the answer is that there is not one moment in our life when we do not see the proof of the inner life; only, we do not look for it. All the different means of communication such as telegraphy and telephone and radio, all the new machines and inventions which make people marvel at what mankind has accomplished are, if man would only realize it, nothing but a poor imitation of what this human body is! Man is the center of joy, of happiness, of peace, of power, of life, and of light. Man is a phenomenon far greater than any other mechanism, if only he had the patience and perseverance to explore himself. But what we do is to explore others. We think it is very important to analyze things, and the analysis of human nature we call psychology. Man analyses everyone except himself, and therefore true psychology is never reached; because the real psychology is to analyze oneself first, and when one's self is analyzed, then one is able to analyze others.
