Involuntary bio-chemical and physical response is as good a place as any to broach the idea of 'hermetic bodywork' with one's own personal reckoning and on their own terms. Introducing macro-micro whatevers and fractal principles by which the ideas can be explored is really simple on a physical/internal level. It gets bogged down in the words, but the practice of those really simple methods gives every individual their unique understanding and insight.
It becomes a mess when someone tries to expand on the simplicity and profundity of the personal experience/understanding while trying to sell you something.
