“Seth material” search engine (Jane Roberts)

The chemical and electrical construction of the human individual opens other pathways, and requires other activities in other fields than those with which the conscious ego is familiar. The mechanics are not important, but as dreaming is partially caused by chemical poisons that make dreaming a necessity for physical survival, so there are other mechanisms of this kind that are actually doorways, built within and natural to the physical mechanism, that at the same time necessitate experience upon other fields of reality.

Many purposes are thereby served. You have a focus in many more worlds than you know. One is a conceptual energy force reality which is much more than some theoretical world of ideas, but a reality in which individual energy is used in a constant manipulation of idea or concepts into constructions that, while not physical in your terms, is nevertheless a vivid and actual, concrete field of manipulated and applied force in which matter may be, but is not always, an end result.
