The DNA is a large high-weighted molecule of 51.18", seen as a twisted double thread or spiral staircase. It's composed by two acid and sugar chains, alternated and combined at intervals: thymine (T) always paired with adenine (A), and cytosine (C) always paired with guanine (G). Paired components are grouped and create a sequence which produces aminoacids, the bases for proteins.
The DNA has also been described as a cosmic serpent "that lives in water and emits photons, like an aquatic dragon spitting fire", emitting and absorbing pulses as if it were a system communicating with major organisms.
I Ching is an analogy of the ways of all things in the creation, of all processes and reflections in nature. The word I was initially a pictogram for lizard or cosmic dragon, and is usually translated as change, to describe the evolution of patterns (yin-yang) and rhythms in chi (vital energy) over time.
Change is unchangeable: life is unfolded throughout time by going through changes. I Ching offers a panorama of reality in change itself by associating three transformative sequences to Fu Hsi's trigrams:
An exponential sequence
Life profussion inside of a geometric view of an expanding universe. What it is, is expressed by 2 (ying and yang), producing 4 (brigrams), 8 (trigrams) and 64 (hexagrams).
A heavenly sequence
Solstices and equinoxes are associated to trigrams. In the ordering assigned by Fu Hsi, Chien is Summer (Heaven, metal, South in the Western world), Li is Autumn (flame, fire, East), Kun is Winter (Earth, North), and K'an is Spring (abyss, water, West).
An earthly sequence
It describes chi's natural unfolding during 12 annual seasons. Light and darkness increase or decrease as the energy comes from Earth or the base of hexagrams: from Kun towards Chien, to come back to Kun and so on, cyclicly... Yang hemicycle starts in Fu (Return) and ends in Chien, and yin hemicycle starts in Kou (Coupling) and ends in Kun.
In I Ching as much as in the DNA's structure, the changes in sequences seem to happen according to some predictable ordering: the cosmos, Earth, geometry, genetics... But the oracle is a special reference because it allows seeing through the mutable lines the chance coming along with chi's fluctuations in the empty. Mutations reflect those emitted and received energies, as they impulse or are about to impulse new actions in upcoming sequences of situations. Without a doubt, the nature of change is an enigma, and we found in I Ching a graphic way to represent it.
