This secret was revealed in one of the greatest bestselling books of all time which was written by the famous American author, Napoleon Hill, in his book; “Think And Grow Rich”.
He made a crucial statement on the tenth chapter, The Mystery Of Sex Transmutation. Mr. Hill clearly explained the importance of the sex glands in productivity. He stated emphatically in the fifth paragraph that “the emotion of sex contains the secret of creative ability.
Destroy the sex glands, whether in man or beast, and you have removed the major source of action. For proof of this, observe what happens to any animal after it has been castrated. A bull becomes as docile as a cow after it has been altered sexually. Sex alteration takes out of the male, whether men or beast, all the fight that was in him. Sex alteration of the female have the same effect”.
