(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.
