What the body wants is not a straightforward proposition, as within the body are a multitude of chaotic forces and interests, which can express themselves in contradictory desires and intentions, all of which are further complicated by emoting and cognition.
Stooping to listen, one may catch the ghostly ringing of a socially cultivated desire, or the pining of a colony of bacteria injected into the stomach by industry.
A novel virus, driven and spread in part by the complex forces of interrelating cognition and desire, reveals the interrelatedness of and integration of intellectual, spiritual, emotional, and instinctual systems, and the need for the harmonious functioning of those systems.
It is not enough to simply stoop and listen to one's body as it cries out from infection, as addressing those immediate needs may lead to further complications, and the building up of momentum of those complications.
One also has to enter intellectually into the field of research and best practice, as there may not be enough time to traverse that idiosyncratic chain of trial, error, and revelation in one's individual person.
