Understanding this mystery of human nature and studying the secret of the whole life, the Sufi has traced that spirit in its essence, belonging to the Source of all things. He calls that spirit Kabir, or Kibriyy, the Ego, or Egoistic. It has taught the Sufi a moral, that not only man but even God is displeased by self-assertion. And the manner that he adopts in order not to arouse that agitating spirit he calls Inkisar, meaning selflessness.
