29:0.1 Of all the universe personalities concerned in the regulation of interplanetary and interuniverse affairs, the power directors and their associates have been the least understood on Urantia. While your races have long known of the existence of angels and similar orders of celestial beings, little information concerning the controllers and regulators of the physical domain has ever been imparted. Even now I am permitted fully to disclose only the last of the following three groups of living beings having to do with force control and energy regulation in the master universe:
29:0.2 Though I deem it impossible to portray the individuality of the various groups of directors, centers, and controllers of universe power, I hope to be able to explain something about the domain of their activities. They are a unique group of living beings having to do with the intelligent regulation of energy throughout the grand universe. Including the supreme directors, they embrace the following major divisions:
29:0.3 The Supreme Power Directors and Centers have existed from the near times of eternity, and as far as we know, no more beings of these orders have been created. The Seven Supreme Directors were personalized by the Seven Master Spirits, and then they collaborated with their parents in the production of more than ten billion associates. Before the days of the power directors the energy circuits of space outside of the central universe were under the intelligent supervision of the Master Force Organizers of Paradise.
29:0.4 Having knowledge about material creatures, you have at least a contrastive conception of spiritual beings; but it is very difficult for the mortal mind to envisage the power directors. In the scheme of ascendant progression to higher levels of existence you have nothing directly to do with either the supreme directors or the power centers. On certain rare occasions you will have dealings with the physical controllers, and you will work freely with the supervisors of morontia power upon reaching the mansion worlds. These Morontia Power Supervisors function so exclusively in the morontia regime of the local creations that it is deemed best to narrate their activities in the section dealing with the local universe.
