“Seth material” search engine (Jane Roberts)

(The combination of) thought, emotion, and desire creates form, possesses energy, (and) is made of energy. It will show itself in as many ways as possible. You only recognize the physical materializations, but as mentioned earlier in this book, you send pseudoforms of yourself out from yourself of which you are not aware; and this is completely aside from the existence of astral travel or projection, which is a much more complicated affair.

There are other much easier methods. I have explained to some degree the way images are constructed out of an available field of energy. You perceive only your own constructions. If a “ghost” wants to contact you therefore, he can do so through telepathy, and you can yourself construct the corresponding image if you desire. Or the individual might send you a thought-form at the same time that he telepathically communicates with you. Your rooms are full now of thought-forms that you do not perceive; and again, you are as much a ghostly phenomenon now as you will be after death. You are simply not aware of the fact.
