This is a Morphic-field, not an energy-body. It connects a few inches below the base of the spine (other Morphic-fields connect in the same area, including ones relating to functionality, presence, matter and energy).
Most people have this Morphic-field using a definition of “self” which includes separation from, and opposition to, “others”, which makes it a significant component of “ego” as a negative, as well as containing information which defines body as being in opposition to Ultimate-selves. They also have other “ego-points” (smaller Morphic-fields related to this one) around the body, caused by non-ideal connections or interactions between different parts of the body systems. Some of the data above was discovered by Max Sandor.
Beings in very good condition have this Morphic-field using definitions such as being part of the whole of an eco-system, being pan-existent, being one of many beings, having a unique location within a larger area with many beings in it, having good relationships with other levels and other types of beings etc. These non-polarized definitions are much better for both the body and the Ultimate-self owning it, and enable improvements to many other parts of the body systems.
