The ways of the Jedi is copied from a religon, not Star Wars as a whole. Lightsabre combat employs the basic techniques of kendo, which is Japanese fencing. And lightsabres are very much like shinai's, which are kendo swords. Shape wise and all, shinai are made out of wood, usually bamboo. I dont know about the rest. Seems original to me. Original or not, they still rule.
