Eight hundred million people, i.e. about one third of those alive today [1946], will be mercilessly condemned to starve, if at the final hour it is not possible to produce the practical examples necessary to open the eyes of those who do not perceive the differences between different current-sources, from which, depending on the choice of trifling starting impulse - life or death originate.

This is reason why the Austrian government was requested merely to make a suitable location available at their expense, where in all peace and quiet and with the help of familiarised assistants, it would be possible by practical examples to reveal to the world at large and to expose publicly the ur-causes of this indescribable misery and appalling poverty.

Since there would be little point in providing a long and detailed preliminary scientific explanation, a simple example that can be understood by everyone will suffice to explain the nature of this form of motion, which we all have to thank for all we see around us or are otherwise aware of. Only one thing remains hidden from us and that is the 'reactive' temperature-form. This actually involves higher undetectable temperature differences, which reveal the presence of two opposing 'ur-primordial' primary substances, which explain the profound mystery of the genesis of all life or inner motion. Since this will invalidate all forms of contemporary belief and science, it seems to be the real reason why an explanation is shunned in such circles.

But now to the example mentioned earlier: In the 'normal' course of cellar fermentation two different (reactive and active) temperature differences (this two-fold concept will be described later) trigger off that special form of motion which, after the expulsion of the less valuable in two opposite directions, gives rise to ethereal energetic matrices that also operate in the same two directions. A destructive force that self-intensifies by the square is activated, whose function is to return to the Earth as quickly as possible, everything that would inflict damage on that which explains all life and movement, and which moves in the other direction (vertically) towards its objective.
