When we speak, "Krsna," you should understand " Krsna " means God, the Supreme Being. " Krsna," the etymological meaning is "the all-attractive." Without being all-attractive there is no meaning of God. It is not that God is attractive only to certain class of men. No. God is attractive for all classes of men, unless he is animal. Animal does not know what is God and what is the attraction of God. He does not know. But human being, in the human society, at least in the civilized human society there is a certain idea of God. Either you follow Christianity or Vedic principle of Mohammedan religion or even Buddha religion, there is conception of God. There is an attempt to understand God. That is human society.
