The administrative center of Satania consists of a cluster of architectural spheres, fifty-seven in number—Jerusem itself, the seven major satellites, and the forty-nine subsatellites. Jerusem, the system capital, is almost one hundred times the size of Urantia, although its gravity is a trifle less. Jerusem's major satellites are the seven transition worlds, each of which is about ten times as large as Urantia, while the seven subsatellites of these transition spheres are just about the size of Urantia.

The seven mansion worlds are the seven subsatellites of transition world number one.

This entire system of fifty-seven architectural worlds is independently lighted, heated, watered, and energized by the co-ordination of the Satania Power Center and the Master Physical Controllers in accordance with the established technique of the physical organization and arrangement of these specially created spheres. They are also physically cared for and otherwise maintained by the native spornagia.

The seven major worlds swinging around Jerusem are generally known as the transitional culture spheres. Their rulers are designated from time to time by the Jerusem supreme executive council. These spheres are numbered and named as follows:

Number 1. The Finaliter World. This is the headquarters of the finaliter corps of the local system and is surrounded by the receiving worlds, the seven mansion worlds, dedicated so fully to the scheme of mortal ascension. The finaliter world is accessible to the inhabitants of all seven mansion worlds. Transport seraphim carry ascending personalities back and forth on these pilgrimages, which are designed to cultivate their faith in the ultimate destiny of transition mortals. Although the finaliters and their structures are not ordinarily perceptible to morontia vision, you will be more than thrilled, from time to time, when the energy transformers and the Morontia Power Supervisors enable you momentarily to glimpse these high spirit personalities who have actually completed the Paradise ascension, and who have returned to the very worlds where you are beginning this long journey, as the pledge of assurance that you may and can complete the stupendous undertaking. All mansion world sojourners go to the finaliter sphere at least once a year for these assemblies of finaliter visualization.
