your order of creature life in spirit and personality manifestations, differing only in certain physical features and in the fact that they are nonfusible with Thought Adjusters.

As to just why this type of creature is never able to fuse with the Adjusters of the Universal Father, I am unable to say. Some of us incline to the belief that the Life Carriers, in their efforts to formulate beings capable of maintaining existence in an unusual planetary environment, are confronted with the necessity of making such radical modifications in the universe plan of intelligent will creatures that it becomes inherently impossible to bring about permanent union with the Adjusters. Often have we asked: Is this an intended or an unintended part of the ascension plan? but we have not found the answer.

Series three—mortals of Adjuster-fusion potential. All Father-fused mortals are of animal origin, just like the Urantia races. They embrace mortals of the one-brained, two-brained, and three-brained types of Adjuster-fusion potential. Urantians are of the intermediate or two-brained type, being in many ways humanly superior to the one-brained groups but definitely limited in comparison with the three-brained orders. These three types of physical-brain endowment are not factors in Adjuster bestowal, in seraphic service, or in any other phase of spirit ministry. The intellectual and spiritual differential between the three brain types characterizes individuals who are otherwise quite alike in mind endowment and spiritual potential, being greatest in the temporal life and tending to diminish as the mansion worlds are traversed one by one. From the system headquarters on, the progression of these three types is the same, and their eventual Paradise destiny is identical.

The unnumbered series. These narratives cannot possibly embrace all of the fascinating variations in the evolutionary worlds. You know that every tenth world is a decimal or experimental planet, but you know nothing of the other variables that punctuate the processional of the evolutionary spheres. There are differences too numerous to narrate even between the revealed orders of living creatures as between planets of the same group, but this presentation makes clear the essential differences in relation to the ascension career. And the ascension career is the most important factor in any consideration of the mortals of time and space.

As to the chances of mortal survival, let it be made forever clear: All souls of every possible phase of mortal existence will survive provided they manifest willingness to co-operate with their indwelling Adjusters and exhibit a desire to find God and to attain divine perfection, even though these desires be but the first faint flickers of the primitive comprehension of that “true light which lights every man who comes into the world.”

The mortal races stand as the representatives of the lowest order of intelligent and personal creation. You mortals are divinely beloved, and every one of you may choose to accept the certain destiny of a glorious experience, but you are not yet by nature of the divine order; you are wholly mortal. You will be reckoned as ascending sons the instant fusion takes place, but the status of the mortals of time and space is that of faith sons prior to the event of the final
