“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.
