“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.

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.
