Dai Mai Girdling Vessel: Horizontal Meridian Tensegrity, Toroidal Dantian Circulation, and Core Lumbar Stabilization in Classical Neigong
To understand the [Meridian Theory in Traditional Chinese Medicine](https://en.wikipedia.org/wiki/Meridian_(Chinese_medicine)), one must visualize the human body as a dynamic matrix of vertical energetic conduits. Twelve primary organ channels travel longitudinally between the extremities and the trunk, while the primary extraordinary vessels—the *Ren Mai* (Conception Vessel) along the front midline, the *Du Mai* (Governing Vessel) along the dorsal spinal column, and the *Chong Mai* (Thrusting Vessel) piercing the core vertical axis—all reinforce this up-and-down polarity.
