economy and industry secular science instructed and taught the opposite 'winding'. Therefore, in lieu of the evolution-fostering (ennobling) spirit, it raised and reinforced the demon in the form of development-impeding electricism, as if by conveyor belt, to such an extent that the magnetism-generating Earth, which moves in cycloid-spiral-space-curves, is now incapable of neutralising the decomposive energies and their effects produced by millions upon millions of human beings. [The Energy Evolution - Harnessing Free Energy from Nature, Magnetism - Electricism]
It is hardly worth elaborating further about the opposite case in which the components of pressural force that produce decomposive energies predominate by almost 100%, i.e. the formative (cooling) components of suctional force have been totally disregarded. Therefore with the best will in the world, no flowing magnetism (levitism) can come into being, due to the almost complete lack of the most fundamental prerequisites for growth and increase. On the contrary, everything that now grows (solidifies) already contains the germ of decay, so that in every seed, whether or not it serves an increase in raw or subtle -energetic- matter or even in energy itself, the fiendish demon must rise again. [The Energy Evolution - Harnessing Free Energy from Nature, Magnetism is the Function of Levitism and Electricism is the Function of Gravitism]
"Cases are increasing in which children are born with a human form, but are not really human beings ... are not reincarnated, but are human forms filled with a sort of natural demon.
Imagine what people would say if they heard that we say there are people who are not human beings." [Rudolf Steiner, Faculty Meetings with Rudolf Steiner]
