We practice our swing to learn the parts and how to put them together into one swing. During that practice, we might come to believe that one of those parts is the key to making the entire swing work, and get stuck on referring back to that one feeling when we play.
While the swing is composed of identifiable parts, the feeling of the whole swing is not of each of these parts as they parade by in succession from takeaway to finish. The whole swing has a feeling of its own, one feeling in itself.
The whole swing feeling is bigger than any of the smaller parts, but it is the same in that like the parts, it too is one thing with its own one feel. That whole swing feeing is the feeling you play golf with.
Every touring professional, or any high-performing athlete in any sport, is a technical player in practice, but a feel player in performance. They practice their technique, but then trust what they have practiced when they play, and just perform.
