Hi @ura-soul. No- I haven't seen that book. But it might be a similar technique? This one may look simple as I've presented it here in a written blog, but once you start using it in daily or weekly life it can radically change the structures on a deep level. Whenever I do it, it's an extremely deep, hot morphing kind of experience. A LOT happens! Especially if you can work it in more than a couple of times per week.
