“Seth material” search engine (Jane Roberts)

The mind will be found to be closely allied with the spacious present. The mind’s capabilities, if studied, would lead man into a realization of these other fields of actuality of which I have spoken. The mind deals with intangibles, but it does not deal with unrealities. Again, the validity of an actuality is not to be determined by its appearance within matter alone. The ingredients of matter are first of all intangible ingredients, and the study of the mind and a study of the processes by which the mind creates its dream images could lead to a basic understanding of the manner in which man subconsciously produces the physical images of his own material universe.

You can see that the inner self is much more spacious and unlimited than the ego self, and that while divisions occur they may vary, and the boundaries of the inner self constantly change.
