This is basically known as the Zen philosophy. Part of the Eastern tradition of philosophy, they recognized eons ago that in order to become a master at, say, Archery, you had to practice until you could “shoot without shooting”. This is basically a confusing way of saying you have committed the practice to muscle memory. You have done it so many times that you no longer need to think about the individual steps, the “chunks”, as it were.
I guess the adage lives on: everything old is new again.
