“Seth material” search engine (Jane Roberts)

Many of these planes of actuality can never be explored by any physical vehicle. They would appear as incomprehensibly vast as your single planet would appear to a single fly, who set out to examine it. Perception of its characteristics would be impossible. To you physical objects would seem so far separated in space that you would lose your way, and not perceive realities as they there existed at all.

You would not be able to perceive a sufficient amount of data to make any deductions. This is not to say that such planes or fields of actuality cannot in some manner be perceived, but they will escape physical perception or exploration. In dreams, when the self is somewhat free from camouflage, perhaps it is possible for the self then to travel spontaneously into such fields of actuality; but since they are as bizarre to the self as is the dream world itself, then there is no way, usually, for the sleeper to distinguish between the universe of dreams or other actualities.

There are many more. It is known now that the physical organism exists as many things. It even exists as radio waves, and to creatures who cannot perceive matter but can perceive radio waves, your physical body appears quite differently than it does to you. The whole physical organism contains checks and balances of which your scientists are still not aware, and I must also mention that for all its mandy-pamby, astrology has a strong basis, although it is only one small portion of the whole story, and not indeed the whole kettle of tales.

The physical organism protrudes into many fields of actuality, and is to some extent perceived within these fields, and influences those fields as they influence the physical organism. It is because you conceive of the body as existing within one field only that you have not had more success in dealing with human illness.
