When we understand the Soul’s Nadial Plexus is the blueprint to the physical CNS, it is clear that deep emotional pain, shock and trauma are directly inter-related to Soul Damage.
The Nadial Plexus is generally a term used to refer to the epicenter of the "feeling" sensory functions of the energy receivers located in the entire Nadial Body. This plexus is also the intrinsic part of the Heart Complex, the feeling intelligence, so it refers to the "center of one's heart". It is where one would sense the deepest sensations of heart based feeling.
