As previously mentioned animal food constitutes an unfolding of vibration too strong for the human organism. So, in order for this food to be converted to nourishment, it must produce a surplus of energy, that is, an amount of energy that it in reality, because of its stage in evolution, has grown away from being able to supply without risk to health. So the digestion of animal food means a permanent overexertion for the human being and ultimately becomes the fundamental cause of the majority of organic illnesses. It is in order to remedy this that the boiling of food has been devised. What then really happens during boiling?
      In order to understand this we must remember that all substances consist of life-units, and that the step in evolution of the animal life-units is too near our own on the ladder of evolution. Being assimilated as nourishment in the human organism meant therefore an unnatural death for these units. And against an unnatural death all normal life-units fight. Through the assimilation of the animal life-units as nourishment into the organism, this organism must take up the fight against the resistance or death-throes of the life-units. Only when this is finished and the small organisms of the life-units are killed does actual digestion begin. But one must not believe that this digestion applies to the small killed organisms. On the contrary. These are decomposed in a quite natural way like all other corpses by a process of putrefaction. Corpses cannot be "digested", but these killed organisms contain a certain percentage of those life-units that are so far back in evolution that their life and well-being means being assimilated as nourishment in an organism. These cannot therefore be killed by this assimilation but instead, by virtue of this, acquire conditions favourable to life. So we are dealing here with two forms of life-unit. For practical reasons we will call the former "A life-units" and the latter "B life-units". A lifeunits are those whose organisms are killed, and B life-units are those whose organisms acquire life through assimilation as nourishment in an organism. Through the process of putrefaction of the organisms of the "A life-units", the "B life-units" encapsulated within these are liberated. These are then guided in a living state by the being's digestive organs, in which they are assimilated as food, to the areas and localities in this being's organism in which they can each find their particular conditions favourable to life. The killed organisms of the "A life-units" on the other hand are guided by the digestive organs out of the organism again. And it is these remains of corpses or stinking products that we know as "excrement".
      So animal products are in reality merely indirect food, as it is only these life-units' life-units that are direct food. And in order to liberate the latter life-units the former must therefore be killed. And it is a matter of course that nourishment based on this process of killing is far heavier or more difficult than nourishment where this is not needed. Here one must naturally take the individual's step in evolution into account. If we, for example, go down to the beast of prey we will see that the organism of such animals is to a particular degree based on and built for the promoting of the above-mentioned process, but as one reaches further in evolution the organisms become more and more refined, and more and more lose, to a corresponding degree, their ability to promote this process. In human beings this ability is degenerating at a very rapidly increasing rate. This therefore means that as a human being develops, it becomes increasingly difficult for the process of killing to be carried out through his organism. This has in turn resulted in his finding other ways through which this process can be promoted. The most fundamental or comprehensive of these is precisely boiling. In the boiling of products what happens is that the A life-units are killed, and only the B life-units are left behind, since these are to a great extent unaffected by boiling. So when people today cook their food it is to free their organisms from undertaking this process of killing. This process of liberation therefore means relief for the organism. The human being feels that he has not nearly as much difficulty in "digesting" the cooked products as he has in digesting the raw ones. He has realised that boiling makes the products "tender". This "tender" state is due only to the fact that the "A life-units" are already killed before they are eaten or assimilated as food in the organism. But this does not alter the fact that they are all the same corpses that are eaten and that the life-units that are living and therefore constitute the true nourishment for the organism can, as previously mentioned, be released or liberated only through the putrefaction or decomposition of these corpses. As this process of putrefaction, in addition to liberating the "B life-units", just like all other processes of putrefaction, is a combination of all the substances that are destructive and damaging to the organism, such a permanent state cannot in the long run be free from damaging effects on the advanced organism. The goal of evolution is therefore, among other things, to lead individuals forward to a state in which they can more and more assimilate the "B life-units" directly and not indirectly through a prior process of putrefaction or decomposition of corpses through which the organism at the same time, to a corresponding degree, must permanently be a well of poison, a sewer or a residence for all materials, substances or vibrations lethal, detrimental or damaging to life.
