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 the Supreme Lord, the material energy or Durga Devi is weak. Therefore, being weak, it is the eternal occupational duty of the living entity to surrender to Supreme. In the Vedic society, the weaker class serve the stronger class. Therefore there was no envy of the stronger by the weaker class of men. So perfect society, or Vedic society does not eliminate competition of stronger and weaker but it eliminates envy since everyone is weak before Supreme Powerful God or Krishna.
