36:2.11

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.
