The ordinary person knows that after deep sleep he is calm, reposed, his feeling is better, his thoughts clearer. The condition of Hal, or Samadhi, the highest condition, is the same as that of deep sleep, the difference being only that it is experienced at will. The difference between the perfect person and the ordinary person is only this, that the perfect person experiences consciously what the imperfect person experiences unconsciously. Nature provides all with the same experience, but most people are unconscious of the experience, which is to their disadvantage.
