37:5.1

The High Commissioners are Spirit-fused ascendant mortals; they are not Adjuster fused. You quite well understand about the universe-ascension career of a mortal candidate for Adjuster fusion, that being the high destiny in prospect for all Urantia mortals since the bestowal of Christ Michael. But this is not the exclusive destiny of all mortals in the prebestowal ages of worlds like yours, and there is another type of world whose inhabitants are never permanently indwelt by Thought Adjusters. Such mortals are never permanently joined in union with a Mystery Monitor of Paradise bestowal; nevertheless, the Adjusters do transiently indwell them, serving as guides and patterns for the duration of the life in the flesh. During this temporary sojourn they foster the evolution of an immortal soul just as in those beings with whom they hope to fuse, but when the mortal race is run, they take eternal leave of the creatures of temporary association.
