During the First World War, a sex-ridden civilization which had sought intense pleasures found intense pain. Did it learn the implicit lesson? No! It plunged more wildly than ever in the quest of sexual joy, only to find still worse agony in the Second World War. The more it has wasted the gift of life, semen, the more it has lost the essence of life, blood. Semen is white blood. Nature has punished man's careless dissipation of the one with a forced loss of the other. The time has come to teach the lesson of sexual responsibility in clear words. If humanity refuses to learn and obey spiritual laws, the horror of a third world war, compared with which the second will be mere child's play, cannot be escaped.
