The Melchizedeks have the general oversight of the fourth group of seven primary spheres in the Salvington circuit. These worlds of the Life Carriers are designated as follows:
- The Life Carrier headquarters.
- The life-planning sphere.
- The life-conservation sphere.
- The sphere of life evolution.
- The sphere of life associated with mind.
- The sphere of mind and spirit in living beings.
- The sphere of unrevealed life.
Each of these primary spheres is surrounded by six satellites, on which the special phases of all the Life Carrier activities in the universe are centered.
World Number One, the headquarters sphere, together with its six tributary satellites, is devoted to the study of universal life, life in all of its known phases of manifestation. Here is located the college of life planning, wherein function teachers and advisers from Uversa and Havona, even from Paradise. And I am permitted to reveal that the seven central emplacements of the adjutant mind-spirits are situated on this world of the Life Carriers.
The number ten—the decimal system—is inherent in the physical universe but not in the spiritual. The domain of life is characterized by three, seven, and twelve or by multiples and combinations of these basic numbers. There are three primal and essentially different life plans, after the order of the three Paradise Sources and Centers, and in the universe of Nebadon these three basic forms of life are segregated on three different types of planets. There were, originally, twelve distinct and divine concepts of transmissible life. This number twelve, with its subdivisions and multiples, runs throughout all basic life patterns of all seven superuniverses. There are also seven architectural types of life design, fundamental arrangements of the reproducing configurations of living matter. The Orvonton life patterns are configured as twelve inheritance carriers. The differing orders of will creatures are configured as 12, 24, 48, 96, 192, 384, and 768. On Urantia there are forty-eight units of pattern control—trait determiners—in the sex cells of human reproduction.
The Second World is the life-designing sphere; here all new modes of life organization are worked out. While the original life designs are provided by the Creator Son, the actual outworking of these plans is intrusted to the Life Carriers and their associates. When the general life plans for a new world have been formulated, they are transmitted to the headquarters sphere, where they are minutely scrutinized by the supreme council of the senior Life Carriers in collaboration with a corps of consulting Melchizedeks. If the plans are a departure from previously accepted formulas, they must be passed upon, and endorsed by, the Creator Son. The chief of Melchizedeks often represents the Creator Son in these deliberations.
Planetary life, therefore, while similar in some respects, differs in many ways on each evolutionary world. Even in a uniform life series in a single family
