“Seth material” search engine (Jane Roberts)

(There are four recognized [electrical] brain waves, and in speed they range upward from 0 to 26 and more Hertz units, or cycles per second. These rhythms can vary somewhat, and are best thought of as areas of activity. Brain waves overlap. Very simply, delta brain waves are connected with dreamless sleep, theta with creativity and dreams, alpha with a relaxed alertness and changing consciousness; beta — the fastest — with concentration, and with an intense focus upon all of the challenges [and anxieties and stresses, many would say] faced in the ordinary daily world.

(We read that in ordinary terms highly creative people [like Jane] usually generate large amounts of theta and low-alpha waves pretty constantly while doing their thing. Measuring and recording brain waves is a complicated task, however; not only is it important which areas or lobes of the brain are monitored — if not all of them — but because of the mechanical limitations of the EEG itself much that goes on in the brain is necessarily missed. In addition, the two hemispheres of the individual brain often show variations in electrical energy states. But most importantly, we think, while the EEG can indicate broad categories of brain activity, it can hardly probe the participant’s very individual and subjective content of mind within this camouflage [physical] reality. Nor at this time, given the minimum premise that Jane’s speaking for Seth constitutes any indication of “paranormal” activity, do we think that her performance could be identified as such per se on the graphs of her brain waves. The state of “EEG art” isn’t that advanced yet [if it ever will be]. Presumably, however, when speaking for Seth, Jane would show definite changes in all frequency areas in both hemispheres, with the theta and delta ranges altered the most. We also think that her EEG readings would vary once again when she spoke or sang in Sumari, her trance “language.”

(Our curiosity about such speculations led me to plan this appendix shortly after the 711th session was held, and I asked Jane if Seth could eventually offer some insights about the brain’s electrical reality. He finished dictating Volume 2 of “Unknown” Reality in April 1975, and we finally got around to the session I wanted six and a half months later.
