When your irritable and conductive neurons meet your sensitive and effective acupoints, you will be fully fired up. in between there is a shield that protects the normal functioning and senses what is stranger from that is dangerous.
Upon conception, we are granted with these facilities, and our body will be built upon by three generations’ accumulated know-how facilities. Only through high learning and education, or self-discipline and deep meditation practice, you will know what you are made of from what your body has, and how you are robotic from how you be creative.
The questions are: are nerve fibers meridian wires? Is cytoplasm meridian line/shield? Are free nerve endings made for acupoints?
Neurons are such mini-self conscious inertias, just as acupoints are like gravitational angles. Neurons are matters and acupoints are the points that matter to the real matters.
