“Seth material” search engine (Jane Roberts)

The units are just beneath the range of physical matter. None are identical. However, there is a structure to them. This structure is beyond the range of electromagnetic qualities as your scientists think of them. Consciousnesses actually produces these emanations, and they are the basis for any kind of perception, both sensory in usual terms and extrasensory.

These emanations can also appear as sounds, and you will be able to translate them into sounds long before your scientists discover their basic meaning. One of the reasons why they have not been discovered is precisely because they are so cleverly camouflaged within all structures. Being just beyond the range of matter, having a structure but a nonphysical one, and being of a pulsating nature, they can expand or contract. They can completely envelop, for example, a small cell, or retreat to the nucleus within. They combine qualities of a unit and a field, in other words.

These units then obviously change constantly. If we must speak in terms of size, then they change in size constantly as they expand and contract. Theoretically there is no limit, you see, to their rate of contraction or expansion. They are also absorbent. They do give off thermal qualities, and these are the only hint that your scientists have received of them so far.
