“Seth material” search engine (Jane Roberts)

Planes can and do intermix without the knowledge of the inhabitants of the particular planes involved. I want to get away from the idea of a plane being a place. [...] A plane may be a time. A plane, believe it or not, may be only one iota of vitality that seems to exist by itself. A plane is something apparently divided from the rest of the universe for a time and for a reason. A plane may cease to be. A plane may spring up where there was none. A plane is formed for entities as patterns for fulfillment on various levels. A plane is a climate conducive to the development of unique and particular capacities and achievements. A plane is an isolation of elements where each one is given the most possible space in which to function.

[Many of] the flying saucer appearances come from [such] a plane, [one] that is much more advanced in technological sciences than earth at this time. However, this is still not a mental-science plane. [...] Now, so strong is this tendency for vitality to change from one apparent form to another, that what you have here in your flying object is something that is actually, as you view it, not of your plane or of [whatever] plane of its origin … The atoms and molecules that structurally compose the UFO, and which are themselves formed by vitality, are more or less aligned according to the pattern of its own territory. Now as the craft enters your plane a distortion occurs. [...]

[...] 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.

Planets have been used as planes and used again as other planes. A plane is not a cosmic location. It is oftentimes practical that entities or their various personalities visit one plane before another. This does not necessarily mean that one plane must be visited before another. [...]

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.

[...] When sciences progress on various planes, then visitations become less accidental and more planned. Once the inhabitants of a plane have learned mental-science patterns, then they are to a great degree freed from the more regular camouflage [physical] patterns. This applies to “higher” planes than mine, generally speaking, although mine is further along in these sciences than your own.

[...] These vehicles cannot stay on your plane for any length of time at all. The pressures that push against the saucer itself are tremendous … The struggle to be one thing or another is very great on any plane. To conform to the laws of a particular plane is a practical necessity, and at this time the flying saucer craft simply cannot afford to stay betwixt and between for any indefinite period.

[...] [In the early sessions, incidentally, Seth used the word “plane” often, but not long afterward began the general changeover to “reality,” which for the most part we like better. However, note at the end of these excerpts from the 16th session the meanings and delineations he found within that word “plane” — even though he regarded it as our term.])

[...] As science advances on various planes the inhabitants learn to travel between planes occasionally, while carrying with them the [camouflage] manifestations of their home stations …

In fact, the analogy of a plane with an emotional state is much more valid than that between a plane and a geographical state — particularly since emotional states take up no room.
