41:2.6

These beings of the energy realms do not directly concern themselves with energy as a component factor of living creatures, not even with the domain of physiological chemistry. They are sometimes concerned with the physical preliminaries of life, with the elaboration of those energy systems which may serve as the physical vehicles for the living energies of elementary material organisms. In a way the physical controllers are related to the preliving manifestations of material energy as the adjutant mind-spirits are concerned with the prespiritual functions of material mind.
