773. "Cosmic chemistry" thus constitutes the colouring of the I. But since this colouring is an expression of the knowledge, thought, will and ability of the I, it is identical to the I's life. Since life thus constitutes a product of thought and will, it has a specific purpose. The I wants something or other to be triggered off. This desire or wish is in turn the same as a sensation of "hunger". When the triggering has taken place, the wish is fulfilled and the I feels a sense of "satisfaction". We will then be able to see that these two factors, already described in "Livets Bog", belong to the very first cosmic constituents of life itself. Without these two chief constituents, life itself would be an impossibility.
      All forms of manifestation, from the faintest little sigh in the microbeings of microbeings, to the immense forms of floods of energy that govern worlds, suns and milky ways in macrobeings, are all without exception a revelation of "hunger" and "satiation". There is absolutely nothing that is directly accessible to sensory perception, nothing that can be seen, heard, felt, thought or experienced, that is not the expression of a degree of "hunger" and a degree of "satiation". This "hunger" and "satiation" begins or originates in "X2", and appears here as what we know under the term "primordial desire". Since this is the very beginning of the revelation or the proclamation of the I's existence or life, this desire will therefore be revealed here as the very first existing "something" through which we can recognise the main reality in the I or the "divine something" that we call "life". The "primordial desire" is therefore a "substance" of which "life" consists. It is the primary, main material behind every form of life. And we will therefore define it here in "Livets Bog" as "life substance no. 1"
