Mind Like the Moon

  This refers to the need to be constantly aware of the totality of the opponent, and his/her movements, just as moonlight shines equally upon everything within its range. This means that one shouldn't only watch some parts of the opponents body, such as the hands or feet, than the entire body. With the development of this attitude, the consciousness will be immediately aware of any openings in the opponent's defenses.
  Clouds blocking the light of the moon are likened to nervousness or distractions. These distractions stop the light from shining on everything. Likewise, they make comprehension of a reaction to the opponent's moves more difficult than they need to be.
