Prior to meeting Yoda, Luke_s expectation of greatness and what makes one a Jedi was connected with one_s ability to fight or operate heavy machinery. He called Dagobah _a slimy mudhole_. Both of these views transformed. _Wars do not make one great_. Yoda teaches Luke mastery of thoughts, feelings, focus and commands Luke to _feel the force around you. Here, between you and me, the tree, the rock, everywhere, yes... even between you and the ship. Jedi uses Force for knowledge and defense, never for attack._
