Relax the mind
Receiving external stimuli tends to agitate the
receptors in the brain in such a way that it becomes difficult to "read" the
incoming information clearly.
I like to think of our mind as being like a still
pond, smooth as glass. Every bit of information we perceive creates a ripple similar to
those made when an object is dropped into the water. The size of the ripple depends on the
mass of the object contacting the surface of the water.
If the surface of the water is smooth with few or no
ripples, the reflection in the water creates a very clear and accurate image of the world
above. If the water is agitated by many objects touching it's surface, as when it's
raining, the image of the world above becomes difficult to discern.
A relaxed mind, free from unnecessary thought, functions
much like the calm pond. It's able to perceive the outside world clearly. Every movement
of your opponent is then as recognizable as a drop of water striking the smooth surface of
a calm pond. When the mind is so full of thought, like a pond when it's raining, it
becomes difficult to "read" the incoming information clearly.
