“Seth material” search engine (Jane Roberts)

This error may become habitual, coloring all other psychological structures, and resulting in unfortunate and dangerous physical constructions. They are extremely destructive errors, and have many causes. The physical construction is then perceived by the outer senses as threatening and fearful, and influences through the outer senses the inner individual, so that he begins a vicious circle in an attempt to form further, more threatening physical constructions to combat the earlier ones. And the greater the number of such destructive physical constructions, the greater his expectation of further fear.

Understand that awareness is the criteria, however. There is no law limiting the number of psychological structures available to you, but because of your present development, and because of this alone, you are hampered. Experience or lack of it on various fields has not yet been possible, so practically speaking you have a limited number of basic psychological structures to deal with; and your perception, clear psychological understanding, intuitive comprehension of, and manipulation and psychological constructions of these basic structures, will determine the validity of your material constructions that will then form your environment.
