In the lectures given in Dornach in Autumn 1923 (Man as Symphony of the Creative Word), Rudolf Steiner pointed to the special nature of the cow as the animal which embodies the mysteries of the digestive process in an archetypal way. In the Agriculture Course, he described the growth of plant life on the surface of the Earth as a higher form of digestion within Nature. Both these considerations may help to explain the following.
The quadruple stomach of the cow is the site of the most comprehensive cosmic alchemy on Earth. A cow’s blood is the carrier of its cosmic individuality, its cowness (The Group Soul). By including some blood in the preparation we appeal to this high spiritual being for its powerful support. In using the contents of the cow’s stomach, we facilitate the continuation of the process of disenchantment of the elementals which had already begun with digestion – in particular of those elementals which had previously been enchanted into the growth processes of the fodder plants. The stimulus given thereby to these processes also produces an enlivening of and support for the re-enchantment of the elementals into the small creatures which inhabits the compost heaps (which are treated with the preparation), or the cultivated earth on which it is sprayed. The essential aim of this preparation is the stimulation of the desired processes and support which this gives to the request for help from the four groups of “very useful” elementals.
