“Seth material” search engine (Jane Roberts)

Within these units there is, again, a propensity for growth and organization. Within a literally infinite field of activity, meaningful order arose out of the propensity for significance. Briefly, certain units would settle upon various kinds of organization, find these significant, then build upon them and attract others of the same nature. So were various systems of reality formed. (Pause.) The particular kind of significance settled upon would act both as a directive for experience and as a method of erecting effective boundaries, within which the selected kind of behavior would continue. The units can and do intermix, yet because of the propensity for selectivity and significance, whole groups of them will “repel” other whole groups, thus providing a protective inner system of interaction.

The same thing with variations happened with your own race, and for that matter is happening. In the past as you think of it historically, several groups experimented along those lines. At those times the individual consciousness became so entranced with its own experiences, however, that the clear-cut, steady, and conscious communication with the mass consciousness went underground, so to speak. It became available to those who looked for it, but the same kinds of psychological organization did not result on those occasions.²
