“Seth material” search engine (Jane Roberts)

It is always interaction which is important. Even the mental enzymes themselves are interchangeable as far as the principle behind them is concerned, though for practical purposes they maintain separate and distinct qualities in their materializations in one plane. That is why it is possible for some human beings to experience sound as color, or to see color in sound. Granted this is not characteristic experience, but if the mental enzymes were not interchangeable in principle, then this experience would not be possible for any. Light would never be heard for example, sound would never be seen. Nor is color usually heard, nor sound usually seen.

It is unfortunately true that the dominant present ego can be degraded on your plane to an amazing degree, through for example brainwashing and so forth. However this situation, while bad enough, is not as dire as you might think. When you are considering the human personality as a thing of this time only and destroyed by death, then its disintegration for any reason seems truly a tragic thing. And it is tragic.

I am quite sure, I know for a fact, that beings from other planes have appeared on your plane, sometimes on purpose and sometimes completely by accident. As in some cases human beings 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 to your plane, as the few 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 many sciences just dealing with locomotion. Had the human race for example 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. 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.
