“Seth material” search engine (Jane Roberts)

It is self-propelled, self-perpetuating as a psychological energy unit. It will indeed materialize itself upon the physical plane simultaneously and withdraw itself simultaneously, as I have explained earlier. Your time sense gives it and all matter the appearance of durability. The energy that composes the smallest or any physical unit, passes through the physical field where the outer senses can no longer perceive it. Some, and a large amount, of this energy passes through the physical field so that you do not perceive it at all, taking form that you do not distinguish, and that cannot be harnessed on the physical level. And this is where your scientists get the idea of entropy.

With the present heating system, high expectations would have increased its efficiency. Low expectations would have decreased its efficiency. Your fear of commitment was indeed an element here. You have both steadily doubted your practical efficiency in a material universe, and you will continue to do so, for with your present attitudes you will not test your efficiency. Or if you dare test it, your fears will defeat you, and only serve to convince you further of this inefficiency.
