It's kind of the same thing though. Obi-Wan says to Luke, "use the force" and he lets the force guide him. Obi-Wan isn't specifically telling him anything other than turn off the computer and let the force guide your aim. He's not specifically telling Luke where and when to fire.
In TFA Kylo says to Rey "I can teach you the ways of the force" and then she realizes that's when she needs to abandon her fear and let the force guide her. She and Luke both finally embrace the force as the powerful ally it is, at those particular moments.
Ben tells Luke to trust the Force. Luke then switches off his targeting computer and trusts the Force.
Kylo is telling Rey she needs a teacher. Rey then proceeds to ignore what Kylo is saying and let the Force guide her directly, defeating the guy who professed she needed him to teach her.
How is that at all the same thing?
It feels like we agree, because I have no problems with what you just said. I was just talking about your statement that teaching is worthless when I believe it's not. You still need training in order to learn how to let the Force guide you.
I'm not actually convinced this is actually true or that it has ever been truly important to good triumphing over evil in the Star Wars universe.
- Anakin's Jedi training was insufficient to keep him from falling to the dark side. He certainly was never concerned with listening to the Force's guidance; he wanted to wield the Force as a weapon to achieve his goals.
- Almost every formally trained Jedi failed to survive the Jedi purge, and we're told the Jedi's ability to tap into the Force was diminished, presumably through Palpatine's influence.
- Luke was formally trained, but in the end ignores the instructions of his masters to defeat Vader and wins in the end
precisely by refusing to participate in the struggle.
- Vader doesn't even actually use the Force to defeat the Emperor; he just opens his heart to compassion for his son, an act that requires no training whatsoever and in fact goes directly against his own Sith training.
- Yet again, every one of Luke's students-in-training either is slaughtered or is Kylo Ren and turns to the dark side.
- Rey, the only Force-sensitive person we've encountered in the films who as far as we know has had no formal training, defeats Kylo Ren
simply by tapping into the guidance of the Force.
There's nothing saying that anything the Jedi or Sith have ever told us about the Force is actually pristine advice, and in fact the "formal" ways of both the Jedi and the Sith have been pretty consistently fallible.
