“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].

Excellence will show itself through the arts, cultural creativity, technological or sociological accomplishments. The species tries to fulfill its great capacities. Each physical body in its own way is like the world. It has its own defenses and abilities, and each portion of it strives for a quality of existence that will bring to the smallest parts of it the spiritual and biological fulfillment of its own nature.
