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 should watch just part of
the opponents body such as the hands or feet, rather watch 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 and reaction to the opponent's moves more difficult
than they need to be.
