“There are all kinds of biological reactions between bodies that go unnoticed, and they are all basically of a social nature, dealing with biological communications. In a fashion, viruses again, are a way of dealing with or controlling the environment. These are natural interactions, and since you live in a world where, overall, people are healthy enough to contribute through labor, energy, and ideas, health is the dominating ingredient – but there are biological interactions between all physical bodies that are the basis for that health, and the mechanisms include the interactions of viruses, and even the periods of indisposition, that are not understood.
“All of this has to do with man’s intent and his understanding. The same relationships, however, do not only exist between human bodies, of course, but between man and the animals and the plants in the environment, and is part of the unending biological communication that overall produces the vitality of physical experience.”
