Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering. I sense much fear in you.
Yoda: Yes, run! Yes, a Jedi’s strength flows from the Force. But beware of the dark side. Anger, fear, aggression; the dark side of the Force are they. Easily they flow, quick to join you in a fight. If once you start down the dark path, forever will it dominate your destiny, consume you it will, as it did Obi-Wan’s apprentice.
Luke: Vader… Is the dark side stronger?
Yoda: No, no, no. Quicker, easier, more seductive.
Luke: But how am I to know the good side from the bad?
Yoda: You will know… when you are calm, at peace, passive. A Jedi uses the Force for knowledge and defense, NEVER for attack.
Luke: But tell my why I can’t…
Yoda: No, no! There is no “why”.
Yoda: I am wondering, why are you here?
Luke: I’m looking for someone.
Yoda: Looking? Found someone, you have, I would say, hmmm?
Yoda: Help you I can. Yes, mmmm.
Luke: I don’t think so. I’m looking for a great warrior.
Yoda: Ohhh. Great warrior.
[laughs and shakes his head]
Yoda: Wars not make one great.
Luke: I can’t. It’s too big.
Yoda: Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well 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 and binds us. Luminous beings are we, not this crude matter. You must feel the Force around you; here, between you, me, the tree, the rock, everywhere, yes. Even between the land and the ship.
Yoda: You must unlearn what you have learned.
Yoda: Ready are you? What know you of ready? For eight hundred years have I trained Jedi. My own counsel will I keep on who is to be trained. A Jedi must have the deepest commitment, the most serious mind. This one a long time have I watched. All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing. Hmph. Adventure. Heh. Excitement. Heh. A Jedi craves not these things. You are reckless.
