Here is the passage from the Barbara Brennan material:
"Many people have the erroneous idea that this HEF field is like the
layers of an onion. It is not. Each level penetrates through the body
and extends outward from the skin. Each successive level is of a
'higher frequency' or a 'higher octave.' Each extends out from the
skin several inches farther than the one within it of lower frequency.
The odd-numbered levels are structured fields of standing,
scintillating light beams. The first, third, fifth, and seventh levels
of this field are structured in a specific form. The even numbered
levels-- the second, fourth, and sixth--are filled with formless
substance/energy. The second level is like gaseous substance, the
fourth is fluid like, and the sixth is like the diffuse light around a
candle flame. It is the unstructured level of the energy field that
has been related to plasma and dubbed bioplasma. Remember, these are
not scientific terms we use here because scientific experimentation
has not yet proven what it is. But for lack of a better term, we shall
use the word bioplasma. The bioplasma in all three of the unstructured
levels is composed of various colors, apparent density, and intensity.
This bioplasma flows along the lines of the structured levels. It
correlates directly with our emotions.
The combination of a standing light grid with bioplasma flowing
through it holds the physical body together in its form, nurtures it
with life energy, and serves as a communication and integration system
that keeps the body functioning as a single organism. All of these
levels of the human energy field act holographically to influence each
These levels, or energy bodies as many people call them, cannot be
considered less real than our physical body. If all of your energy
bodies are strong, charged, and healthy, you will have a full life in
all areas of human experience. If your energy field is weak at any
level, you will have difficulty having experiences that are associated
with that level, and your life experience will be limited. The more
levels or bodies that you have developed, the fuller and broader your
life experience will be."
The layers of an onion explanation is a useful description for our linear mind and the construct of this dimension, earth plane and current society that creates relationships through 3d space and through linear time. So this is an easy way to understand the holding patterns and stored unresolved information affecting the layers of the HEF. It also can be useful to understand that the layer concept is also related to the individual’s journey - what are they ready to let go of and accept, and how that changes their perspective in this 3D level of existence.
All is connected simultaneously. Holographically. Each part is a representation of the whole and IS the whole. To give an idea of how all is affected, let’s use the example of a bed sheet. Let’s say it is being held at each corner by a person. Someone places a brick on the sheet. All the threads in the sheet change relationship to one another. Add another object. Each object reacts to the other, plus all the threads of the sheet. Simultaneous communication.
This is my simplified explanation. Enjoy!
