"That which is nearest is least observed. The Atman is the nearest of the near, therefore the careless and the unsteady mind gets no clue to it. But the person who is alert, calm, self-restrained, and discriminating ignores the external world and, diving more and more into the inner world, realizes the glory of the Atman and becomes great."

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 Atman, 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.
