Somebody wrote in as below, with a question that references this blog post from earlier this week:
Q: Thanks for writing up the bone lightup effect filling from below. It's extremely interesting tho I cannot feel what you say yet. But I am wondering since you brought out repulse monkey as a tai chi move that can develop bone awareness or that neon energy thing, but is there any special move for that in the xingyi context as opposed to tai chi only?
A: Yes, there certainly is. And one fuck of a powerful practice it is, I must say. This is something I taught all along, from a while back but nobody paid a whole lot of attention. However I hesitate to cite it now in this context, just because, if you haven't done all the basic foundational work, you'll certainly get great energetic effects from this training move (I will cite specifics below) but unless you are very advanced in your energy work and relaxation, etc, all the basics of (my type of) Xingyi and/or Tai Chi SLO/Singularity work it's frankly unlikely that you'll get the pelvic fill-from-below bone lightup effect right off the bat. So you will feel disappointed and give up as 99.99% of people do, and I understand that. You can't pay your cable bill with bone lightups! However it's extremely interesting and over time can be integrated as a martial arts attribute the way all the great historical masters have said. I'm working on a writeup about Sagawa on this later, it's in progress. The trouble with all this blogging is that I'm giving everything away in fragments, and then when I come to write it all up as another book, people will ignore it saying Oh that's just a cobbling up of his old blog posts. So you get penalized for trying to give away stuff free.
Anyway cut to the chase for now, yes there is a nearly exact Xingyi functional equivalent for the Tai Chi Repulse Monkey that specifically sets up and triggers the pelvic fill-from-below bone lightup. It is my video from the top of this post. Remember as you watch that when I introduced it I did not make specific reference to this bone lightup thing because it was totally beyond the audience. And probably still is. But you asked. Combine the physical teaching of this move (in the video above) with the explanations in my last 3 or so blog posts here to get the full picture of how this XYQ move works for the effect under discussion.
The basic mechanics for this move are also described in the book version Radical Xingyi Energetics.
