Hello Cady,
We don't know each other. I teach aikido in the Netherlands and also lead an ILC study group. I'm curious if you have shown this clip to Sifu. I have demonstrated some of this material to Joshua who found it very interesting but I have not had a serious talk with Sifu directly. In ILC language this is a reasonable demonstration of maintaining neutral on the POC and also wha.t some in aikido would refer to as kokyu ho. It is still a shame however that these sorts of clips do not explain enough of the relevance of the Shen Fa to give a bridge to a martial function. For me it is the same as seeing the 3 planes of movement with a compliant partner, hard to understand ,but easy to feel the why and wherefore. I have worked with Akuzawa and Dan Harden over the years but my exposure to ILC has begun to cement certain ideas about aikido as an internal art that have been forming for the last 10 years.
(I'm a bit slow, must be age related ;-) )
regards,
Alec
