It's a great feeling indeed. For me, I feel and imagine, that my hands are floating freely in space. That I have no arms per se, that there is no club - only a swinging 'point of force', in my hands, and the feel of lag and downward compression.
The mind is indeed, in the hands. Or perhaps the hands are in your mind. When you can really 'see' in your mind, you can just let the swing happen. When you can really feel the 'swinging' of the entire club, the heavy club, you will feel so much control. Totally balanced control.
Just like shooting a basketball. A reaction to the target, and the image in your mind.
