“Seth material” search engine (Jane Roberts)

“The universe as you think of it contains innumerable planes, all taking up, in your terms, the same amount of space. The forms within these planes are in constant motion, as are the planes themselves. There is a continual exchange of energy and vitality, in other words, of actual atoms and molecules between one plane and another … the interaction and movement of even one plane through another results in effects that will be perceived in various ways … as necessary distortive boundaries, in some cases resembling a flow as if a plane were surrounded by water, or in other cases a charge as of electricity. But on each plane the effects … of this interchange of energy will take on the camouflage [physical appearance] of the particular plane.

(And from the 40th session:) The tissue capsule is actually an energy field boundary … At the same time it protects the whole self from certain radiations which do not here concern you. No living consciousness exists on any plane without this tissue capsule enclosing it … To some inhabitants of other planes [realities] that have access to your plane, all that can be seen of you is this capsule, since such inhabitants have had no experience in your particular type of camouflage [physical] construction. Therefore your camouflage patterns are invisible to them, but the tissue capsules are not.¹

“… forms vary on different planes, are visible or invisible according to your own situation. A form that may be perceived by you as solid may be seen merely as an electrical unit on another plane, or as color on a third. You, for example … are perceived by others on other planes at this moment, but to them you are not seen in the form with which you are familiar.

“Using the senses developed on a particular plane to perceive its characteristic camouflage patterns, it is almost impossible to see beyond these boundary effects. The inner senses are inherently equipped to do this, but for many reasons they do not. The appearance of an expanding universe is also caused, therefore, by this distortive boundary effect …

[...] As he said in the 29th session for February 26, 1964: “Later I will attempt to show you where the boundaries are — though (with a laugh) there really are no boundaries — that form a variety of such planes [realities] into a sphere of relation in which, to some extent, cause-and-effect operates as you understand it. [...] I will speak of the entity, the personalities, the reincarnations, the diverse personality fragment groupings, the planes with which you are similar or can understand, and ultimately try to deal with your questions, implied if not spoken, as to where entities came from to begin with.
