“Seth material” search engine (Jane Roberts)

Therefore, there is what I will call the negative interval, when one pulsation has vanished from your plane and another is about to take its place. Alone, each negative interval may be negligible, but taken en masse this adds up until there is as much negative matter as there is positive matter.

Now. This physical matter on your plane we will call positive matter. To the field of negative matter, your positive matter would be termed negative. Obviously we have much material to cover, positive and negative. The point is that perception is the criteria for what you call matter. You do not perceive the negative interval. You do not perceive continuous creation of matter.

Your physical plane is not the only plane given to the manipulation of matter. It is, however, the focal point of such planes, and they are closely interwoven. The other two planes form what you may think of as the outer rims. I suggest your break.
