Nature's Eternal Laws

"Stay close to nature and its eternal laws will protect you."

A sailing friend who has battled cancer introduced me today to the alternative dietary therapy of Max Gerson. Here is a capsule of that philosophy, from his website.

"Throughout our lives our bodies are being filled with a variety of disease and cancer causing pollutants. These toxins reach us through the air we breathe, the food we eat, the medicines we take and the water we drink. 

 "With its whole-body approach to healing, the Gerson Therapy naturally reactivates your body's magnificent ability to heal itself - with no damaging side-effects. "

The Wiki post on Gerson indicates that "the therapy is considered scientifically unsupported and potentially hazardous, and has been blamed for the deaths of patients who substituted it for standard medical care. I have no way of knowing the efficacy of the Gerson Therapy, but my friend says it saved his life. 

What I find particularly interesting is this summary by Max Gerson, "Stay close to nature and its eternal laws will protect you."

What would it mean to "stay close to nature" in business? Are there natural, eternal laws in business? And, if there are, what effect would they have?
