"...I am greatly pleased to hear from you that you have increased the selling books five times more in Chicago centre. That is very good news to me. Yes, there must always be competition, that gives life, that cannot be separated from life. Sanatan dharma means the strong will utilize the energy of the weak, the weak must serve the strong, that we see everywhere, is it not? Who can deny? So that competitive spirit makes us strong, otherwise it is a society of weak men only, and what is the good of such society? But if you ask anyone are you weak or strong, he must answer that he is weak—he cannot control even his toothache, what to speak of his death. Therefore, in fact, it is a society of weak men—everyone is weak before Durga Devi or the material energy. If you see sometimes her picture, the foolish materialist is being held by the claws of her tiger-carrier, while she pierces him to death with her trident weapon. She has got ten arms, each with weapon, she is so strong, but we are so weak that simply by piercing with her trident, the three-fold miseries, adhibhautika, adhidaivika, and adhyatmika, the foolish materialists are all defeated! And before Krishna, Durga devi is very weak—Krishna is the controller of Durga. So Krishna is the strongest: sattyam sattvavatam aham, "I am the strength of the strong." Therefore, being weak, it is the eternal occupational duty of the living entity to surrender to Krishna, that's all. In the surrendering to Krishna, if everyone does it, still, the brahmanas will be served by the lower castes, the kings will be served by vaisyas and sudras, the vaisyas will be served by the sudras, and the sudras will serve all higher castes—there is still utilizing the weak by the strong—but feeling themselves always very much weak in comparison to Krishna, the whole society services the Strongest, therefore there will be no envy of the stronger by the weaker class of men. So perfect society, or Vedic society, does not eliminate competition—competition, stronger and weaker, must be there—but it eliminates envy, because everyone is weak before Krishna. Is that clear?"
