Ordinary so-called "death", or the kind of "death" that is announced in newspaper obituaries, is thus merely a purely temporary, necessary, practical measure or a maintenance principle. As regards real death, this is so gentle and concealed that it can be seen and observed really only by the advanced researcher. The fact that this death is so gentle and imperceptible in its transitions is due exclusively to the circumstance that it is not the consequence of any catastrophe or mutilation, neither is it the result of wear and tear or old age. Its existence, on the contrary, is due to an eternally changing rhythm that is released through the individual's primordial desire and appears externally as a correspondingly eternally alternating "hunger" and "satiation". This has its origin in the I's superconsciousness, that is to say its X2, and expresses itself as a powerfully increasing desire to experience the opposite existence to the one the particular I at the time finds itself in. This desire is all the stronger the more the I or the being is satiated with its present existence. This same desire stretches out towards its culmination, whereupon it decreases and reaches its stage of least expansiveness where it began, after which it begins to increase towards its culmination again, and so on. This rhythmical movement released through the primordial desire is called, in my main work Livets Bog, the spiral or cycle of evolution.
