Alternate flow of space levels exerts antigravity influence.  Antigravity can annul gravity within a local frame; it does so by the exercise of equal force presence.  Antigravity is also employed in Havona in the organization of the material functions and the spiritual activities of these enormous worlds.  It operates only with reference to material gravity, and it is not the action of mind. 
Prevents gravity from converting all energy into matter. Given a sufficient duration of retarding influence, gravity would eventually convert all energy into matter were it not for two factors: First, because of the antigravity influences of the energy controllers, and second, because organized matter tends to disintegrate under certain conditions.  Ultimatonic energies sometimes exhibit antigravity behaviour.  Evolving energy has substance; it has weight, although weight is always relative, depending on revolutionary velocity, mass, and antigravity.
