“Seth material” search engine (Jane Roberts)

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.

Now back to the point. When however sciences progress on various planes, then visitations become less accidental and more planned. However, since the inhabitants of each plane are bound by the materializations or materialized patterns of that plane, they bring this particular materialization pattern or camouflaged vitality pattern with them. Certain kinds of sciences cannot operate without it. When the inhabitants of a plane have learned mental science patterns, then they are to a great degree freed from the more regular camouflage patterns. This applies to a higher plane than mine, generally speaking, although my plane is further along in this science than your own.
