this movie gave the best speech and brief summary of wat the force is.
"Look at me, judge me by my size do you? And where you
should not, for my ally is the force and a powerful ally it is.
Life creates it, makes it grow. Its energy surrounds us,
combines us. Luminous beings are we not just crude matter.
you must feel the force around you.
through you, through me, the tree, the rock and yes. even
between land and ship."
Greatest speech ever! :)
