I just confirmed something I've been wondering for years: what route does chi follow in the body and where exactly are the meridians. I'm about 90% sure they are inside the blood vessels. This explains several things: 1. Why does chi go directly into a person's heart when you strike them ANYWHERE? 2. Why do a lot of chinese schools incorrectly think chi = blood? 3. Why are blood illnesses the most detrimental to energy training (rather than for example neurological diseases)? I was meditating and just generally relaxing and feeling the electric chi circulating around my body, etc... when someone started banging on our gate. It was freaking 10pm and automatically I got nervous. Then immediately my lower dan tian ball contracted as a fear response and sent chi rushing through my body and into my arms and my palm. Now, here's the fun part: i was in a weird body position where my thumb was for some reason touching my chin - my entire thumb..muscle (??) started contracting and tensing up involuntarily then I felt the chi jump into my chin, go down the vein on the side of my neck and down to points unknown. This continued for a while until I eventually got up to see wtf was going on. So, all my experiences seem to point to the same thing: chi runs through the blood in some way and it's likely that it's actually stored there. The fact that my lower dan tian ball is slightly OFF the spine indicates to me that it might be inside or somehow attached to the abdominal aorta. I need to set up an ultrasound (maybe cat scan?) to see exactly what is growing inside of me and what it looks like.
