Two ideas are psychologically deep-rooted in man: self-protection and self-preservation. For self-protection man has created God, on whom he depends for his own protection, safety and security, just as a child depends on its parent. For self-preservation man has conceived the idea of an immortal Soul or Ātman, which will live eternally. In his ignorance, weakness, fear, and desire, man needs these two things to console himself. Hence he clings to them deeply and fanatically.
