As far as I understand the devil is (as ever) in the details, i.e. what kind of connection is there between the hand and the dantien and what other body connections come into play?
Oh well, small chance we'll ever figure it out without doing a show-and-tell, but just wanted to throw in my 2 cents.
I think that Harden character has been to the "Nether-Lands" quite a few times already(where were you?). Chances are he will be back...Go for it!!! Just my 2cents. ;0)
PS Then maybe you can have some "show" & "tell". Enjoy
