A Jedi was a member of the Jedi
Order, an
ancient order of protectors
united by their
ability to harness the power of
the Force.
Adhering to a doctrine that
favored the light
side of the Force, the Jedi
aspired to attain
a state of inner tranquility
through
calmness and meditation while
avoiding
emotions affiliated with the dark
side of the
Force, such as anger and hatred.
Nevertheless, Jedi philosophy did
not forbid
a Jedi from acting in self-defense
or in the
defense of others. To that end,
the weapon
of a Jedi was the lightsaber, a
blade
composed of pure energy and
different
colors such as blue or green.
