“Seth material” search engine (Jane Roberts)

I am quite sure — I know for a fact — that beings from other planes have appeared among you, sometimes on purpose and sometimes completely by accident. As in some cases humans have quite accidentally blundered through the apparent curtain between your present and your past, so have beings blundered into the apparent division between one plane and another. Usually when they have done so they were invisible on your plane, as the few of you who fell into the past, or the apparent past, were invisible to the people of the past.

This sort of experience involves a sudden psychic awareness, straight from the entity, that all boundaries are for practical purposes only. However, there are indeed many kinds of science. There are a number of sciences dealing just with locomotion. Had the human species gone into certain mental disciplines as thoroughly as it has explored technological disciplines, its practical transportation system would be vastly different, and yet by this time even more practical than it is now. (With amusement:) I am making this point because I want it made plain — this, dear Joseph, is a pun — that when I speak of science on another plane I may not speak of the plain old science that you know.

At a later date I may go into the inhabitants of [those planes] more thoroughly, but as it is I am not very much acquainted with them myself.¹

One note along these lines. A plane — and I am using your term; I will try to think of a better one — is not necessarily a planet. A plane may be one planet, but a plane may also exist where no planet is. One planet may have several planes. Planes may also involve various aspects of apparent time — this particular matter being too difficult to go into right now, although I will continue it later.

[...] I [recently] suggested a project to Ruburt’s class — one that will ultimately illuminate many of the points I am making in “Unknown” Reality. I suggested that Ruburt’s students create a “city”⁹ at another level of reality. [...]

2. A note added six months later: These lines are from a personal session Seth delivered on April 29, 1975, just five days after finishing dictation on “Unknown” Reality (in the 744th session): “Our books, and I am including Ruburt’s, fall into no neat category … In the beginning, particularly, and for that matter now, Ruburt had no accepted credentials. [...]

[...] I am telling you that your own dreams and thoughts and mental actions appear to the inhabitants of other systems like the stars and planets within your own; and those inhabitants do not perceive what lies within and behind the stars in their own heavens.”
