Poučení ze Star Wars - Yoda

Luke's face is upside-down and showing enormous strain.  He stands on 
his hands, with Yoda perched on his feet.  Opposite Luke and Yoda are 
two rocks the size of bowling balls.  Luke stares at the rocks and 
concentrates.  One of the rocks lifts from the ground and floats up to 
rest on the other.

    YODA
  Use the Force.  Yes...

Yoda taps Luke's leg.  Quickly, Luke lifts one hand from the ground.  
His body wavers, but he maintains his balance.  Artoo, standing nearby, 
is whistling and beeping frantically.

    YODA
  Now... the stone.  Feel it.

Luke concentrates on trying to lift the top rock.  It rises a few feet, 
shaking under the strain.  But, distracted by Artoo's frantic beeping, 
Luke loses his balance and finally collapses.  Yoda jumps clear.

    YODA
  Concentrate!

Annoyed at the disturbance, Luke looks over at Artoo, who is rocking 
urgently back and forth in front of him.

Artoo waddles closer to Luke, chirping wildly, then scoots over the 
edge of the swamp.  Catching on, Luke rushes to the water's edge.  The 
X-wing fighter has sunk, and only the tip of its nose shows above the 
lake's surface.

    LUKE
  Oh, no.  We'll never get it out 
  now.

Yoda stamps his foot in irritation.

    YODA
  So certain are you.  Always with 
  you it cannot be done.  Hear you
  nothing that I say?

Luke looks uncertainly out at the ship.

    LUKE
  Master, moving stones around is 
  one thing.  This is totally 
  different.

    YODA
  No!  No different!  Only different 
  in your mind.  You must unlearn 
  what you have learned.

    LUKE
   (focusing, quietly)
  All right, I'll give it a try.

    YODA
  No!  Try not.  Do.  Or do not.  
  There is no try.

 Luke closes his eyes and concentrates on thinking the ship out.

Slowly, the X-wing's nose begins to rise above the water.  It hovers 
for a moment and then slides back, disappearing once again.

    LUKE
   (panting heavily)
  I can't.  It's too big.

    YODA
  Size matters not.  Look at me.  
  Judge me by my size, do you?  
  Hm?  Mmmm.

Luke shakes his head.

    YODA
  And well you should not.  For my 
  ally in the Force.  And a powerful 
  ally it is.  Life creates it, makes 
  it grow.  Its energy surrounds us 
  and binds us.  Luminous beings 
  are we...
   (Yoda pinches 
    Luke's shoulder)
  ... not this crude matter.
   (a sweeping gesture)
  You must feel the Force around you.
   (gesturing)
  Here, between you... me... the 
  tree... the rock... everywhere!  
  Yes, even between this land and 
  that ship!

    LUKE
   (discouraged)
  You want the impossible.

Quietly Yoda turns toward the X-wing fighter.  With his eyes closed and 
his head bowed, he raises his arm and points at the ship.

Soon, the fighter rises above the water and moves forward as Artoo 
beeps in terror and scoots away.

The entire X-wing moves majestically, surely, toward the shore.  Yoda 
stands on a tree root and guides the fighter carefully down toward the 
beach.

Luke stares in astonishment as the fighter settles down onto the shore.  
He walks toward Yoda.

    LUKE
  I don't... I don't believe it.

    YODA
  That is why you fail.
