“The space craft is operated by IS-BEs who use “doll bodies” in much the same way that an actor wears a mask and costume.  It is a like a mechanical tool through which to operate in the physical world.  She, as well as all of the other IS-BEs of the officer class and their superiors, inhabit these “doll bodies” when they are on duty in space.  When they are not on duty, they “leave” the body and operate, think, communicate, travel, and exist without the use of a body.

The bodies are constructed of synthetic materials, including a very sensitive electrical nervous system, to which each IS-BE adjusts themselves or “tune in” to an electronic wavelength that is matched uniquely to the wavelength or frequency emitted by each IS-BE.  Each IS-BE is capable of creating a unique wave frequency which identifies them, much like a radio signal frequency. This serves, in part, as identification like a finger print.  The doll body acts like a radio receiver for the IS-BE.  No two frequencies or doll bodies are exactly the same.

The bodies of each IS-BE crew member are likewise tuned into and connected to the “nervous system” built into the space craft.  The space craft is built in much the same way as the doll body.  It is adjusted specifically to the frequency of each IS-BE crew member.  Therefore, the craft can be operated by the “thoughts” or energy emitted by the IS-BE.  It is really a very simple, direct control system.  So, there are no complicated controls or navigation equipment on board the space craft.  They operate as an extension of the IS-BE.”
