If a person was so great a mystic that he was the greatest Master or if a person was so pious and religious that he was the greatest Saint, still if he did not live the ideal of brotherhood, it would not avail much. Spiritual realization is attained in practical life by observing the ideal of brotherhood. At this time when the world needs the ideal of brotherhood more than ever before in the history of the world, it is our privilege and destiny to do all we can to bring about this ideal in our own lives first, and thus to spread it in the world. Any problem or theory, or doctrine studied, is of no value unless it be practiced. Ten thousand people calling out brotherhood and one person living it is equal or even better. Brotherhood is not a materialistic, it is a spiritual ideal.
