Another shorter reading could use the phrase “Luke’s texts”. One less syllable. Haha.

And okay! I’d appreciate that!

Personally I feel like a good way to explain it would be that it is a unique power that only certain people can do, and it just so happens that Baby Yoda and Rey can (and maybe Rey can because of the dyad stuff). But, I think it is cleaner to explain it coming from the texts. Maybe it was lost knowledge. Or, maybe the Force is more “awake” than it was during the period of the PT-OT. And, it could still be that only certain people can really learn it. But yeah, I don’t think the movie has to get too deep into it. The text explanation feels good enough.
