This is the joy of my martial arts path as well.
In my experience, (This is a Mechanical Elves take on it (I studied Bujinkan Budo Taijutsu, Danzan Ryu, Small Circle, and my Professor Larry Cary said to me one session:
"The movements I am teaching you awaken dormant brain circuitry. When you do these movements, all the old Masters are with you"
That was the moment it really clicked for me.
Later, Soke Hatsumi was quoted in the infamous "Understand? Good. Play!" book -- my favorite quote:
"I am teaching you to wield a sword, even if you have no arms!"
--
The reason is that these two statements allowed me to see what the true nature of my Joy of Movement truely was: I was able to see the Principles of Movement flow through me - (we call this The Mode) - and it was that feeling that was being fully present is what I sought and I feel thats the nature of Mastery of any craft.

I wrote this Haiku a long while back:
Movement and Measure
All is One, flowing through Time.
Another yourself.
