the force:  
 
let us just say that the force is something that the jedi must deal with.  while it has never been properly explained, scientists have theorized it is an energy field generated by living things.  early man suspected it's existence. yet remained in ignorance of it's potential for millennia.
only certain individuals could recognize the force for what it was.  they were mercilessly labeled ; charlatans, fakers, mystics - and worse.  even fewer could make use of it. as it was usually beyond their primitive controls, it frequently was too powerful for them.  they were misunderstood by their fellows - and worse.
the force surrounds each and everyone of us.  some men believe it directs our actions, and not the other way around.  knowledge of the force and how to manipulate it was what gave the jedi his special power
the force is omnipresent
.  it envelops you as it radiates from you.  a jedi warrior can actually feel the force as a physical thing.
it is an aura that at once controls and obeys.  it is a nothingness that can accomplish miracles. no one, not even the jedi scientists, were able to truely define the force.  possibly no one ever will.  sometimess there is as much magic as science in the explanations of the force.  yet what is a magician but a practicing theorist.
you must divorce your actions from your concious control.  try not to focus on anything concrete, visually or mentally.  you must let your mind drift, only then can you use the force.  you have to enter a state in which you act upon what you sense, not on what you think before hand.  you must cease cognition
