Basic evolutionary material life – premind life – is the formulation of the Master Physical Controllers and the life-impartation ministry of the Seven Master Spirits in conjunction with the active ministration of the ordained Life Carriers. As a result of the coordinate function of this threefold creativity there develops organismal physical capacity for mind – material mechanisms for intelligent reaction to external environmental stimuli and, later on, to internal stimuli, influences taking origin in the organismal mind itself.
There are, then three distinct levels of life production and evolution:
- The physical-energy domain – mind-capacity production.
- The mind ministry of the adjutant spirits – impinging upon spirit capacity.
- The spirit endowment of mortal mind – culminating in Thought Adjuster bestowal.
The mechanical-nonteachable levels of organismal environmental response are the domains of the physical controllers. The adjutant mind-spirits activate and regulate the adaptative or nonmechanical-teachable types of mind – those response mechanisms of organisms capable of learning from experience. And as the spirit adjutants thus manipulate mind potentials, so do the Life Carriers exercise considerable discretionary control over the environmental aspects of evolutionary processes right up to the time of the appearance of human will – the ability to know God and the power of choosing to worship him.
It is the integrated functioning of the Life Carriers, the physical controllers, and the spirit adjutants that conditions the course of organic evolution on the inhabited worlds. And this is why evolution – on Urantia or elsewhere – is always purposeful and never accidental.
