“Seth material” search engine (Jane Roberts)

The information contained therein in such bulky printed form, is not physical. It is a matter of knowledge, electromagnetically coded, psychically valid, but you cannot hold knowledge in your hand and perceive it directly. You take its usual transmission in daily life for granted, overlooking the fact that all the physical aspects of its transmission and appearance serve to hide its basic non-materiality, and that words and printed data and moving pictures, all visual or physical symbols, are not the knowledge itself. These only serve as physical carriers. (Long pause.)

Now. In your system of reality you are learning what mental energy is, and how to use it. You do this by constantly transforming your thoughts and emotions into physical form. You are supposed to get a clear picture of your inner development by perceiving the exterior environment. What seems to be a perception, an objective concrete event, independent and apart from you the perceiver, is instead the physical materialization of the perceiver’s own inner emotions, energy and mental environment.
