How will mankind as a whole become fit and healthy? How will it, as an entity, be able to flourish? How will it be possible to built up a "lasting peace" on the basis of the above-mentioned methods and principles? Is it not here obvious that something is lacking? Is it not equally obvious that the ocean of results and solutions in terms of weights and measures of materialistic science is not adequate for the creation of mankind's true happiness? Is it not evident that the understanding of terrestrial mankind's true well-being does not yet have anything to do with real science? Is it not a fact that one lives in the illusion or under the superstition that one can create "lasting peace" through maintaining a permanent state of war? One perfects one's knowledge of murdering, mutilating and destroying, and to this end manufactures the most ingenious technical instruments and machines, and does not understand at all that the effect of all these war-machines is only an attack against matter. Admittedly, they are aimed at mankind's own flesh and blood bodies, but what are flesh and blood? Are they anything other than stone, water and air? The war-machines do not affect, and will never be able to affect, the very cause of war, which is not to be found either in stone, water or air, but exclusively in thought. Of what use is it that so many cultural centres are laid waste, that so many millions of people are killed and mutilated, or that so many standing armies and navies are levied as a "defence"? They do not remove the true cause of war itself, which, as already mentioned, is not to be found in the stone, the water or the air and cannot therefore be found in flesh or blood either, but exclusively in the world that materialistic science denies, namely "the spiritual world".
