The Law of One, Book III, Session 60
Questioner: Is the Earth solid all the way through from one side to the other?
Ra: I am Ra. You may say that your sphere is of an honey-comb nature.
The center is, however, solid if you would so call that which is molten.
Questioner: Are there third-density entities living in the honey-comb areas? Is this correct?
Ra: I am Ra. This was at one time correct.
This is not correct at this present space/time.
Questioner: Are there any inner civilizations or entities living in these areas other than physically incarnate who do come and materialize on the Earth’s surface at some times?
Ra: I am Ra. As we have noted, there are some which do as you say.
Further, there are some inner plane entities of this planet which prefer to do some materialization into third-density visible in these areas.
There are also bases, shall we say, in these areas of those from elsewhere, both positive and negative.
There are abandoned cities.
Questioner: What are these bases used for by those from elsewhere?
Ra: I am Ra. These bases are used for the work of materialization of needed equipment for communication with third-density entities and for resting places for some equipment which you might call small craft.
These are used for surveillance when it is requested by entities.
Thus some of the, shall we say, teachers of the Confederation speak partially through these surveillance instruments along computerized lines, and when information is desired and those requesting it are of the proper vibratory level the Confederation entity itself will then speak.
