What is Yiyuanti? Yiyuanti is a part of the Hunyuan Qi within the human body. It is a form of matter that is invisible, intangible, and formless. Internally, it is perfectly homogeneous and undifferentiated. It is compatible with the physical structure of the brain, centered around the brain's core—specifically, the center of the brain—and extends both inside and outside the brain, reaching throughout the entire body and spreading even beyond it.
Yiyuanti represents the holistic functional state of Hunyuan formed by all the nerve cells in the human nervous system and their associated Hunyuan Qi. Nerve cells serve as the foundation in which Yiyuanti is established, yet Yiyuanti possesses a certain degree of independence and can create a reactive influence on the nerve cells.
