As some insights point, the new concept is the Force can be visualized as stream like a River flowing trough and the one which flows with the river is perfect.
Both Sith (especially them) but the Jedi to were taking from the river making their own little streams (Jedi) or stagnating lakes (Sith) in which Force stagnated and the river was weakened.
They made Force listen to them instead listening the will of the Force themselves.
This was causing inbalance of the Force.

Anyway to not to ovestrech everything for now here is apparent leak of a Luke on meditating stone at Ahch-To.

He has grown in wisdom. I hope this is his true power now .
