What is it that causes inharmony in oneself? Weakness. Physical weakness or mental weakness, but it is always weakness. Very often, therefore, one finds that bodily illness causes disharmony and inharmonious tendencies. Besides there are many diseases of the mind which the scientists of today have not yet discovered. Sometimes people are considered sane whose mind in fact is ill, and as not enough attention is paid to the defects which are inherent in the diseases of the mind, man has never had a chance to notice them in himself. He is continually finding fault with others; whether he works in an office, somewhere in a good position, at home, or anywhere else, he causes inharmony. Nobody realizes this, for to be treated as insane one must first be recognized as insane.
