Electrical Bodies

[hogey11]

Just found this, never noticed it before:

90.5 Questioner: You stated previously that fifth-density entities bear a resemblance to those of us in third density on planet Earth but fourth density does not. Could you describe the fourth-density entities and tell me why they do not resemble us?
Ra: I am Ra. The description must be bated under the Law of Confusion. The cause for a variety of so-called physical vehicles is the remaining variety of heritages from second-density physical vehicular forms. The process of what you call physical evolution continues to hold sway into fourth density. Only when the ways of wisdom have begun to refine the power of what you may loosely call thought is the form of the physical complex manifestation more nearly under the direction of the consciousness.

So our new electrical/chemical bodies will be evolved into according to this...

How could this evolution start to show itself? By electrical, are we talking and extension or upgrade of the nervous system? Will our 'nervous system' gradually extend to that of the planetary mind, thereby making us into a 4D social memory complex?
