Each individual composes the music of his own life. If he injures another, he brings disharmony. When his sphere is disturbed, he is disturbed himself, and there is a discord in the melody of his life. If he can quicken the feeling of another to joy or to gratitude, by that much he adds to his own life; he becomes himself by that much more alive. Whether conscious of it or not, his thought is affected for the better by the joy or gratitude of another, and his power and vitality increase thereby, and the music of his life grows more in harmony.
