The one-point would be center. One does "settle down" (our way of discussing it -- conventional was "weight underside"). Those imply a sinking down. But the whole idea of "ground path" as espoused by others (which was the implication of Graham's post) is actually a heck of a lot more subtle and nuanced. ...
I quite agree at least in how my mind/body system experiences things. As it happens, last night a couple of us co-led class in absence of more senior folks on the mat. I was working w/ folks on how to notice/feel/use 4 principles at different stages in a technique, using our first basic (katatori ikkyo).
I illustrated "weight underside" with the feeling of relaxed heaviness that unbendable arm generates at the point in ikkyo where nage has uke turned and imbalanced but not yet going to the ground (if nage lets up on uke and uke starts to turn back and rise, that feeling of a relaxed "weight underside" is what lets nage keep uke down until nage decides to funekoki forward to fully break uke's balance).
I am just starting to play with ground path stuff but definitely experience that in my body differently from what I was doing last night.
I'm no philosopher, but as a sentient organism, dualism never made much sense to me.
