“Seth material” search engine (Jane Roberts)

(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.

[...] Your focus allows other just-as-legitimate experience to become invisible or unfelt.
