"All motion consists of two components. One component serves inwardness (internalisation) and the other outwardness (dispersion). Both preconditions for motion regulate the eternal flow of metamorphosis (panta Rhei)[1]." [Schauberger, Implosion Magazine, No. 57, p.5.
[[1] panta Rhei:: process of change, everything flows

Rudolf Steiner
“Electricity is light in the sub-material state. Light is there compressed to the utmost degree. An inward quality too must be ascribed to light; light is itself at every point in space. Warmth can expand in the three dimensions of space. In light there is a fourth; it is of fourfold extensions – it has the quality of inwardness as a fourth dimension.” [Rudolf Steiner]
