Rh will creatures of the local systems. Regardless of personal or physical planetary differences, the mental life of all these various orders of mortals is very similar, and their immediate careers after death are very much alike.

But mortal mind without immortal spirit cannot survive. The mind of man is mortal; only the bestowed spirit is immortal. Survival is dependent on spiritualization by the ministry of the Adjuster—on the birth and evolution of the immortal soul; at least, there must not have developed an antagonism towards the Adjuster's mission of effecting the spiritual transformation of the material mind.

It will be somewhat difficult to make an adequate portrayal of the planetary series of mortals because you know so little about them, and because there are so many variations. Mortal creatures may, however, be studied from numerous viewpoints, among which are the following:

Adjustment to planetary environment. Brain-type series. Spirit-reception series. Planetary-mortal epochs. Creature-kinship serials. Adjuster-fusion series. Techniques of terrestrial escape.

The inhabited spheres of the seven superuniverses are peopled with mortals who simultaneously classify in some one or more categories of each of these seven generalized classes of evolutionary creature life. But even these general classifications make no provision for such beings as midsoniters nor for certain other forms of intelligent life. The inhabited worlds, as they have been presented in these narratives, are peopled with evolutionary mortal creatures, but there are other life forms.

1. Adjustment to planetary environment. There are three general groups of inhabited worlds from the standpoint of the adjustment of creature life to the planetary environment: the normal adjustment group, the radical adjustment group, and the experimental group.

Normal adjustments to planetary conditions follow the general physical patterns previously considered. The worlds of the nonbreathers typify the radical or extreme adjustment, but other types are also included in this group. Experimental worlds are usually ideally adapted to the typical life forms, and on these decimal planets the Life Carriers attempt to produce beneficial variations in the standard life designs. Since your world is an experimental planet, it differs markedly from its sister spheres in Satania; many forms of life have appeared on Urantia that are not found elsewhere; likewise are many common species absent from your planet.

In the universe of Nebadon, all the life-modification worlds are serially linked together and constitute a special domain of universe affairs which is given attention by designated administrators; and all of these experimental worlds are periodically inspected by a corps of universe directors whose chief is the veteran finaliter known in Satania as Tabamantia.
