I’m glad you like that quote! I would definitely suggest checking out the Tao Te Ching, if you’re into that kind of stuff. It obviously can apply to life, but you can apply to Star Wars and the Force, too.
Regarding the midi-chlorian quote:
The quote from the 70s, as it is in Rinzler’s The Making of Star Wars goes:
”It is said certain creatures are born with a higher awareness of the Force than humans. Their brains are different; they have more midi-chlorians in their cells.”
But, George had Rinzler edit that quote when he wrote his book, so the original quote would’ve been like this.
”It is said that certain creatures are born with a higher awareness of the Force than humans. Their brains are different.”
So no, midi-chlordans was not an original idea.
The Journal of the Whills was originally a framing device for the early drafts of Star Wars, but George didn’t really expound on what the Whills were. His original idea was that R2 at some point in the future would recount these tales to a Whill, who I guess was a physical being that kept a journal. Which, to me, makes me wonder how that would fit with the whole microscopic world George was talking about in the more recent interview with James Cameron.
And don’t worry man, I have a feeling future films or shows will dive deeper into the Force, and maybe even IX will, who knows? There’s so much content ahead, the Force will inevitably be explored more.
