29:1.1

The Seven Supreme Power Directors are the physical-energy regulators of the grand universe. Their creation by the Seven Master Spirits is the first recorded instance of the derivation of semimaterial progeny from true spirit ancestry. When the Seven Master Spirits create individually, they bring forth highly spiritual personalities on the angelic order; when they create collectively, they sometimes produce these high types of semimaterial beings. But even these quasi-physical beings would be invisible to the short-range vision of Urantia mortals.
