48:2.22 (544.5) While the basic morontia forms of life and matter are identical from the first mansion world to the last universe transition sphere, there is a functional progression which gradually extends from the material to the spiritual. Your adaptation to this basically uniform but successively advancing and spiritizing creation is effected by this selective re-keying. Such an adjustment in the mechanism of personality is tantamount to a new creation, notwithstanding that you retain the same morontia form.
48:2.23 (544.6) You may repeatedly subject yourself to the test of these examiners, and as soon as you register adequate spiritual achievement, they will gladly certify you for advanced standing. These progressive changes result in altered reactions to the morontia environment, such as modifications in food requirements and numerous other personal practices.
48:2.24 (544.7) The selective assorters are also of great service in the grouping of morontia personalities for purposes of study, teaching, and other projects. They naturally indicate those who will best function in temporary association.

48:2.26 (545.1) All morontia transition realms are accessible alike to material and spirit beings. As morontia progressors you will remain in full contact with the material world and with material personalities, while you will increasingly discern and fraternize with spirit beings; and by the time of departure from the morontia regime, you will have seen all orders of spirits with the exception of a few of the higher types, such as Solitary Messengers. 3. Morontia Companions
48:3.1 (545.2) These hosts of the mansion and morontia worlds are the offspring of a local universe Mother Spirit. They are created from age to age in groups of one hundred thousand, and in Nebadon there are at present over seventy billion of these unique beings.
48:3.2 (545.3) Morontia Companions are trained for service by the Melchizedeks on a special planet near Salvington; they do not pass through the central Melchizedek schools. In service they range from the lowest mansion worlds of the systems to the highest study spheres of Salvington, but they are seldom encountered on the inhabited worlds. They serve under the general supervision of the Sons of God and under the immediate direction of the Melchizedeks.
