(Please see previous post for context.)There is another meaning when Yoda responds to Luke’s question.
LUKE: But how am I to know the good side from the bad? YODA: You will know. When you are calm, at peace. Passive.
Yoda is speaking on a mind/metaphysical level. Using “will” as a verb defined as ‘to bring to a certain condition by the power of the will’, his answer can be seen in another way.
“You will [the ability to]know. When you are calm, at peace. Passive.”
On a side note, It’s a complete coincidence that I decided to post this on National Talk Like Yoda Day.
Something I noticed in the Empire Strikes Back. When Luke is training and asks how he would know the good side of the Force from the bad Yoda responds saying, “You will know.” Yoda being an archetype of an extremely high spiritual being would be functioning on multiple realities all at the same time, the physical plane of existence being just one. Another level of reality would be one where he would be able to see the future. He doesn’t mean , “You will know.” He means you will ‘no’, as in you will say no. He saw the future moment when Luke is dueling with Darth Vader when Vader says, “You’re destiny lies with me Skywalker. Obi Wan knew this to be true.” It’s apparent in the acting that Luke briefly becomes angry at this, but thanks to his training he’s able to free himself from said anger. Then, immediately, he’s sort of able to see the negative and positive emotions before him. When Luke says ‘no’, he’s not really responding to Darth Vader at all. He’s really saying ‘know’ as in know the difference between the bad and the good and discard the bad thereby maintaining a calm and centered state; he doesn’t give in to anger or the dark side. Luke may even be aware in that moment that Yoda was in fact telling him the future. There’s a flip flop in meaning and dialogue being done by Yoda and Luke-a kind of crossing in time and space. Yoda was actually saying you will (say) no and in the same way Luke was saying know as in know the difference between the good, light side of the force, and the bad, the dark side. Luke attains a spiritual wisdom resulting from this whole scenario. I also think this takes place in Return of the Jedi during Luke’s confrontation with The Emperor when Luke says no to his attempts at manipulation. Again, he’s really saying know(the difference between the good and bad), but it’s said weakly this time because of The Emporer’s power or influence on him. In addition, in yet another way Yoda’s full line of dialogue, “You will know. When you are calm, at peace. Passive.”, is directly saying what happens to Luke, linearly. This is especially true given Yoda’s inverted speech pattern. Reread, he’s saying, “[first]When you are calm, at peace. Passive. [then]You will [say] know.” This is what Luke goes through in those seconds. There’s an interconnectedness at play with these varied elements. All of this really demonstrates brilliance in storytelling on the part of George Lucas and/or screenwriter Lawrence Kasdan.
Evidence of a connection between Finn and Kylo Ren wherein Finn is Force sensitive and some kind of apprentice. It’s during the battle of Jakku when Kylo Ren turns to look at Finn; in the following shot where Finn is looking back at him you can hear him whisper, “Go ahead.” Then, he immediately nods subtly to the his right. It’s as if he’s saying he hasn’t turned to the light side of the Force, which he has. I can hear it clearly on my Blu-ray copy. They made it almost inaudible but it is there. Of the available clips of this scene online the sound output is equalized where it is almost completely inaudible. The bass level in Kylo Ren’s theme almost overtakes it.
