“Seth material” search engine (Jane Roberts)

Now certain chemical changes must come about in the physical organism before projection can occur. Were it not for these you would still be imprisoned within the corporeal image. You know that dreaming has definite chemical bases, that chemicals built up during periods of waking existence are released through dreams. Not only are they released but they form a propelling action that allows energy to flow in the opposite direction. As chemical reactions allow the body to utilize energy and form physical materializations, so the excess built up then becomes a propelling force, allowing action to flow in what you would term subjective directions.

These projections take a strong propelling force, for you are literally traveling from one dimension or reality to another. And yet you will retain awareness. All of this evening I have been speaking of projections in which awareness is retained, and not of more frequent projections which are usually forgotten.
