“Seth material” search engine (Jane Roberts)

The strange thing about your flying saucers is not that they appear, but that you can see them. 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 …

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.

Now back to the point. 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.

[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. Therefore the camouflage paraphernalia appears, more or less visible, to your own astonishment. 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. Its actual structure is caught in a dilemma of form … between transforming itself completely into earth’s particular camouflage pattern, and retaining its original pattern. The earthly viewer attempts to correlate what he sees with what he supposedly knows or imagines possible in the universe.
