109:3.1 The character of the detailed work of Mystery Monitors varies in accordance with the nature of their assignments, as to whether or not they are liaison or fusion Adjusters. Some Adjusters are merely loaned for the temporal lifetimes of their subjects; others are bestowed as personality candidates with permission for everlasting fusion if their subjects survive. There is also a slight variation in their work among the different planetary types as well as in different systems and universes. But, on the whole, their labors are remarkably uniform, more so than are the duties of any of the created orders of celestial beings.
109:3.2 On certain primitive worlds (the series one group) the Adjuster indwells the mind of the creature as an experiential training, chiefly for self-culture and progressive development. Virgin Adjusters are usually sent to such worlds during the earlier times when primitive men are arriving in the valley of decision, but when comparatively few will elect to ascend the moral heights beyond the hills of self-mastery and character acquirement to attain the higher levels of emerging spirituality. (Many, however, who fail of Adjuster fusion do survive as Spirit-fused ascenders.) The Adjusters receive valuable training and acquire wonderful experience in transient association with primitive minds, and they are able subsequently to utilize this experience for the benefit of superior beings on other worlds. Nothing of survival value is ever lost in all the wide universe.
109:3.3 On another type of world (the series two group) the Adjusters are merely loaned to mortal beings. Here the Monitors can never attain fusion personality through such indwelling, but they do afford great help to their human subjects during the mortal lifetime, far more than they are able to give to Urantia mortals. The Adjusters are here loaned to the mortal creatures for a single life span as patterns for their higher spiritual attainment, temporary helpers in the intriguing task of perfecting a survival character. The Adjusters do not return after natural death; these surviving mortals attain eternal life through Spirit fusion.
109:3.4 On worlds such as Urantia (the series three group) there is a real betrothal with the divine gifts, a life and death engagement. If you survive, there is to be an eternal union, an everlasting fusion, the making of man and Adjuster one being.
109:3.5 In the three-brained mortals of this series of worlds, the Adjusters are able to gain far more actual contact with their subjects during the temporal life than in the one- and two-brained types. But in the career after death, the three-brained type proceed just as do the one-brained type and the two-brained peoples—the Urantia races.
109:3.6 On the two-brain worlds, subsequent to the sojourn of a Paradise bestowal Son, virgin Adjusters are seldom assigned to persons who have unquestioned capacity for survival. It is our belief that on such worlds practically all Adjusters indwelling intelligent men and women of survival capacity belong to the advanced or to the supreme type.
109:3.7 In many of the early evolutionary races of Urantia, three groups of beings existed. There were those who were so animalistic that they were utterly lacking in Adjuster capacity. There were those who exhibited undoubted capacity for Adjusters and promptly received them when the age of moral responsibility was attained. There was a third class who occupied a borderline position; they had capacity for Adjuster reception, but the Monitors could only indwell the mind on the personal petition of the individual.
109:3.8 But with those beings who are virtually disqualified for survival by disinheritance through the agency of unfit and inferior ancestors, many a virgin Adjuster has served a valuable preliminary experience in contacting evolutionary mind and thus has become better qualified for a subsequent assignment to a higher type of mind on some other world.
