The brain is and made up and comprised of many different muscle groups coming into one state, one being that of the mind, the others being of many different cortex levels of consciousness. It is also the filter for all of the attributes of the world and also arranges and runs the chemical formats for the rest of the organs of the physicality.
Looking into the brain from the top of the physicality, it is also the scanner and the inner weaver of consciousness to make up the physical streams from the central nervous system, the autonomic nervous system, the parasympathetic nervous system, etc. It is also in charge of running these systems in a wide awake and fully alert state, keeping everything flying overdrive, and even to its unaccessed abilities being states of stepping into altered realms and otherwise, stepping through many different doors and otherwise. It is a level of the physicality that is truly running the show.
You as you move into the body principle are opening up these chemistries to be heightened, going beyond just a heightened state into a full complete embodied state of consciousness that is allowing for so much more activity and accessibility through your body principle to run forward. And when we get to a heightened state of brain levels all systems are functioning in alignment to further open you and let yourself be so much more open beyond the identities to this world. And be in a much more of a heightened accessibility to off planet support. All the way through this whole universe together as one, to be able to focus to one certain finite state to be aware of what is going on across the galaxies, rather than just keep the head down looking into this world.
