The attraction of gravitation and the repulsion of radiation is nature's simple method of distribution and redistribution of all masses, so that each mass will find its proper position. [See Universal Heart Beat]

It is not proper to conceive either of these apparently opposite forces as two forces.

The south wind and the north wind are not two winds. They are the same wind blowing in opposite directions.

It is more correct to say that gravitation and radiation are processes.

The one motive force which directs these processes is equally divided into opposite effects, but these opposite effects are unequally balanced. [See 14.35.1 - Keely 3 6 and 9]

The unequal divisions of the two opposites totaled together constitute an equilibrium.

The One force never subdivides into any minus expression of force without counterbalancing that minus with an equal and opposite plus. [See Reciprocating Proportionality]

Gravitation is a synthetic process of putting things together, and analytic one of taking them apart.

The chemist uses these processes in every action and reaction.

Consider for example the reduction of iron oxide at high temperature by passing a jet of hydrogen over it.

What happens? The hydrogen falls toward the higher potential of the oxygen of the iron which is sufficiently expanded by the high temperature to absorb the hydrogen, and the hot iron is sufficiently expanded to release the oxygen.

This is an effect of gravitation in respect to the oxygen and the hydrogen.

They unite, they mutually integrate, and freeze into amorphous crystals of such extended orbits that they assume the liquid state known as "water."

On the contrary, it is an effect of radiation in respect to the iron and the oxygen. [The Universal One, Book 02 - Chapter 12 - Gravitation and Radiation, Gravitation and Radiation - page 141]
