Psalms 115:7

None of the physical beings of the central universe would be visible to Urantians. Neither would any of the physical stimuli of those faraway worlds excite a reaction in your gross sense organs. If a Urantia mortal could be transported to Havona, he would there be deaf, blind, and utterly lacking in all other sense reactions; he could only function as a limited self-conscious being deprived of all environmental stimuli and all reactions thereto.

Both orders are nonmaterial beings as regards nutrition and energy intake, but they partake of many human traits and are able to enjoy and follow your humor as well as your worship. When attached to mortals, they enter into the spirit of human work, rest, and play. But midwayers do not sleep, neither do they possess powers of procreation. In a certain sense the secondary group are differentiated along the lines of maleness and femaleness, often being spoken of as “he” or “she.” They often work together in such pairs.

Life on the worlds of the nonbreathers is radically different from what it is on Urantia. The nonbreathers do not eat food or drink water as do the Urantia races. The reactions of the nervous system, the heat-regulating mechanism, and the metabolism of these specialized peoples are radically different from such functions of Urantia mortals. Almost every act of living, aside from reproduction, differs, and even the methods of procreation are somewhat different.

Angels do not have material bodies, but they are definite and discrete beings; they are of spirit nature and origin. Though invisible to mortals, they perceive you as you are in the flesh without the aid of transformers or translators; they intellectually understand the mode of mortal life, and they share all of man’s nonsensuous emotions and sentiments. They appreciate and greatly enjoy your efforts in music, art, and real humor. They are fully cognizant of your moral struggles and spiritual difficulties. They love human beings, and only good can result from your efforts to understand and love them.

These two remarkable creatures were true human beings. They possessed perfect human thumbs, as had many of their ancestors, while they had just as perfect feet as the present-day human races. They were walkers and runners, not climbers; the grasping function of the big toe was absent, completely absent. When danger drove them to the treetops, they climbed just like the humans of today would. They would climb up the trunk of a tree like a bear and not as would a chimpanzee or a gorilla, swinging up by the branches.

On the nonbreathing worlds the animal species are radically unlike those found on the atmospheric planets. The nonbreathing plan of life varies from the technique of existence on an atmospheric world; even in survival their peoples differ, being candidates for Spirit fusion. Nevertheless, these beings enjoy life and carry forward the activities of the realm with the same relative trials and joys that are experienced by the mortals living on atmospheric worlds. In mind and character the nonbreathers do not differ from other mortal types.

The remaining four groups of the Master Physical Controllers are hardly persons within any acceptable definition of that word. These transmitters, associators, dissociators, and frandalanks are wholly automatic in their reactions; nevertheless they are in every sense intelligent. We are greatly limited in our knowledge of these wonderful entities because we cannot communicate with them. They appear to understand the language of the realm, but they cannot communicate with us. They seem fully able to receive our communications but quite powerless to make response.

And when he had finished speaking, no man asked him a question. They went, each one to his sleep.

The Thought Adjuster has no special mechanism through which to gain self-expression; there is no mystic religious faculty for the reception or expression of religious emotions. These experiences are made available through the naturally ordained mechanism of mortal mind. And therein lies one explanation of the Adjuster’s difficulty in engaging in direct communication with the material mind of its constant indwelling.

We are handicapped for words adequately to designate these seven adjutant mind-spirits. They are ministers of the lower levels of experiential mind, and they may be described, in the order of evolutionary attainment, as follows:
