“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 the atoms’ activity in that fashion. [Nevertheless] the agreement takes place at mental levels, and is never completely “set,” though it appears to be. No one perceives the same chair [all of the time], though perhaps a given chair will seem to be “the same one” seen from different angles.
