«The crystal is not, by itself, the power source of the weapon. Like the Force user, the crystal is attuned to the Force. Without that attunement, the crystal is just a rock. And while a non-Force user could probably ignite and wield a lightsaber, provided the crystal was properly attuned to the Force, all that lightsaber would be for him is a shaft of superheated plasma. But for a Jedi, the lightsaber becomes more: it is a manifestation of a Jedi’s connection to the Force.»
