We are brainwashed to believe that diseases are natural and they happen due to microbes and viruses.
In my several notes, I tried to represent alternate perspective.
Here is what Biologist Lewis Thomas said in 1974.
In real life, however, even in our worst circumstances we have always been a relatively minor interest of the vast microbial world. Pathogenicity is not the rule. Indeed, it occurs so infrequently and involves such a relatively small number of species, considering the huge population of bacteria on the earth, that it has a freakish aspect. Disease usually results from inconclusive negotiations for symbiosis, an overstepping of the line by one side or the other, a biologic misinterpretation of borders.
So? Stop blaming microbes for all your failed communications with them! Instead of blaming them, cultivate your immunity! Learn to live in मुनि state! (More here about Muni and Immunity )
Some bacteria are only harmful to us when they make exotoxins, and they only do this when they are, in a sense, diseased themselves. The toxins of diphtheria bacilli and streptococci are produced when the organisms have been infected by bacteriophage; it is the virus that provides the code for toxin. Uninfected bacteria are uninformed. When we catch diphtheria it is a virus infection, but not of us. Our involvement is not that of an adversary in a straightforward game, but more like blundering into someone else’s accident.
Some claims it is diphtheria vaccine that has saved the children! I say, it is post-world war, improved environment that had reduced the cases of diphtheria. Environmental stress reduced, diphtheria not affected by stress-messengers i.e. viruses (bacteriophage) and hence no exotoxins so no diphtheria led deaths.
Lewis Thomas further writes:
I can think of a few microorganisms, possibly the tubercle bacillus, thesyphilis spirochete, the malarial parasite, and a few others, that have a selective advantage in their ability to infect human beings, but there is nothing to be gained, in an evolutionary sense, by the capacity to cause illness or death. Pathogenicity may be something of a disadvantage for most microbes, carrying lethal risks more frightening to them than to us. The man who catches a meningococcus is in considerably less danger for his life, even without chemotherapy, than meningococci with the bad luck to catch a man. Most meningococci have the sense to stay out on the surface, in the rhinopharynx. During epidemics this is where they are to be found in the majority of the host population, and it generally goes well. It is only in the unaccountable minority, the “cases,” that the line is crossed, and then there is the devil to pay on both sides, but most of allfor the meningococci.
Think about it. We need radical new perspective about life. Then only we can see destruction of environment going around. If we don’t nurture environment, we will soon invite another series of epidemic like we did in 18th, 19th and 20th centuries. And no technology would save us!
