“Seth material” search engine (Jane Roberts)

Your ears certainly seem to be permanent appendages, and so do your eyes. You say: “My eyes are blue,” or “My ears are small.” The physical matter of those sense organs changes constantly, however, with you none the wiser. While your body appears quite dependable, solid, [and] steady, you are not aware of the constant interchanges that occur between it and the physical environment. It does not bother you one whit that the physical substance of your body is made up of completely different atoms and molecules than it was composed of seven years ago, [say], or that your familiar hands are actually innocent of any smallest smidgen of matter that composed them [even in recent times past].

You perceive your body as solid. Again, the very senses that make such a deduction are the result of the behavior of atoms and molecules literally coming together to form the organs, filling a pattern of flesh. All other objects that you perceive are formed in their own way in the same fashion.

The differences in motion are so divergent that to you the chair, like your body, appears permanent. The atoms and molecules, like the children, enjoy their motion — solidly sketched in space from your perspective, however, with no “idea” that you consider that motion a chair, or so use it.

You cannot find any given dream location, either, within the brain itself. The solid matter of your world is the result of the play of your senses upon an inner dimension of activity that exists as legitimately, and yet as tantalizingly hidden, as an idea or a dream location.
