THANK YOU Pierre for your generosity! Before I continue reading the material, I wanted to pass on my thanks to you.
On the other hand, is it possible that you could show us how is your gesture representing the information field? Apparently, you have a trademark.
I ask this, because every time the words "information field" appear in a conversation, I automatically guess what could be the gesture that represents this concept, but it is just a guess. Non-verbal language is also important to illustrate an idea, it can even enhance it in many cases.
Well, again THANK YOU for sharing your monumental effort with us! It is very, very much appreciated!

It was not the correct graph. Good catch. It is corrected now in the main file and in the post.

Interesting!! If we have so many viruses around us and inside out bodies right down to the DNA then we ought not to call them "viruses". They are more like self-aware consciousness units connected with the Information field. Not only do they help create and evolve life, in turn assisting in soul development but, on the other hand they also help in body-death via "diseases" when the soul is not making the best use of it.
Chapter 14: Beneficial Viruses
Exogenous viruses
The evolutionary role played by viruses is huge compared to their pathogenicity. Out of the estimated 100 million different species of viruses mentioned in the previous chapter, only about 200[1], in other terms a mere 0.0002%, might cause diseases in humans.
These 200 viruses are only sometimes pathogenic, most carriers are asymptomatic. On top of that, some of these 200 documented viral “pathogens” can also induce beneficial effects; it’s for example the case of the widespread Herpes virus and cytomegalovirus.

Indeed, both Herpes virus and cytomegalovirus exhibits either detrimental or beneficial effects depending on the state of the host’s immune system:
Herpesvirus and cytomegaloviruses are not isolated cases. A virus as common as the flu, believed until recently to be solely a pathogenic agent, is now known to be beneficial by making people more sociable[3]. Notice some subjects in this study had the pro-social benefit of the virus without experiencing any symptoms.
The benefits of viruses are numerous, for example, they enhance the protection of their hosts against bacterial infections[4], they help alternative routes of carbon metabolism during infection[5] and they stimulate the creation of heat shock proteins[6] (HSPs) during times of stress[7]. HSPs are involved in processes as fundamental as:
An even stunning example virus-host synergy comes from parasitic wasps have domesticated viruses that cannot replicate outside the wasps. When injected inside a prey, the viruses neutralized the host’s immune system, so it doesn’t attack the eggs laid by the wasp inside the body of the host:

But maybe the best example of the health benefits induced by viruses is the use of bacteriophages in the treatment of bacterial diseases:
For reference, untreated inhalation anthrax has a fatality rate of 80% or higher[11].
The examples above show how prevalent and vital viruses are in animal life forms, including humans. But the same goes for plants:
One of the main purposes of viruses used by botanists is to improve the beauty of a given plant:
Some of the best characterized beneficial viruses that have been used in plants are those that enhance the beauty of ornamental plants. Tulip breaking virus was the first of a long list of the beautiful viruses, but many other prized ornamentals owe their value, at least in part, to the viruses that infect them[13]

But the beneficial role played by viruses in plants goes way beyond esthetics:
Like in the human genome, viruses have been present in plants genome for a long time:
Endoretroviruses
Although the list of benefit provided by exogenous viruses to their hosts is substantial, it is nothing compared to ERVs.
We’ve seen previously the pivotal role played by ERVs in the apparition of a number of new complex taxa: wallabies, humans, great apes, vertebrates, eukaryotes, jawed vertebrates, teleost fishes Lepidoptera and of course placentals.[16]
For the latter we’ve seen how ERVs were the driver of the apparition of the placentals, including virtually all mammals. Before that reproductive strategies were based on egg-laying.
Like most exogenous viruses, ERVs don’t cause diseases:
But the fact that the numerous viral sequences found in our DNA are not pathogenic doesn’t mean that they are useless archaism. Actually their integration of ERVs in the host’s genome provides benefits:
ERVs are part of what was called “junk DNA”[19], which, for decades, was considered as useless DNA stored away during “evolutionary selection”. This kind of DNA represents about 90%[20] of our genome. But it is now called non-coding DNA because modern genomic has revealed that the junk DNA is not junk at all. One prime example is “gene desert”:
In addition, the common belief that ERVs are non-coding is generally true, but yet there are exceptions for example HERV-K[22] is known to code HDTV[23].
Out of 500 env genes[24], 16 can code for proteins and are abundantly transcribed in key organs like the brain, the thyroid or the adrenal:

In addition to directing genes expression, ERVs have an uncanny ability to modify the existing genome of their hosts, viral and non-viral sequences included:
Despite the recent advent of genomics, there are already numerous examples of beneficial effects induced by endogenous viruses, for example ERVs play a fundamental role in protecting their hosts from ongoing epidemics:
Another example of beneficial effect induced by ERVs is their involvement in the regulation of the expression of useful coding genes:
ERVs are involved in the detection and fight against cancer:
And ERVs are also necessary for embryo development from the earliest stage:
Maybe the fundamental role played by ERVs in morphogenesis as emphasized in the quote above explains why viruses played also a pivotal role in what can be consider as the greatest evolutionary leap, namely the transition from unicellular organisms to multicellular ones:
The above shows the prevalence of viruses in our genetic code and the vital role they play. This perspective provides a different spin to the on-going question about whether viruses are life forms or not. The answer to this question amply depends on the definition one gives to the word “life”.
In the light of the quote above, viruses seem more fundamental than even life itself; they are the information carriers -genetic codes- from which biological life stems. Viruses are more than life; they are the very source of life; they are the informational precursors, the initiators of every single lifeform:
ERVs are involved in a multitude of fundamental functions amongst which, altering and promoting amylase gene, expressing host genes or to facilitating splicing events:
Another example is how transposable elements (sequences of viral origin) are involved in a number of vital processes from immunity to apoptosis (cellular death) regulation[35]:
