In the book Mutant Message Down Under by Marlo Morgan,  a doctor working with an indigenous tribe asked the people to name their physician or medicine person. The villagers replied that no one person played that role because everyone shared in it. They further explained that when the village dealt with sickness, the patient would sit in their midst as they formed a circle. A spokesperson would ask the patient, “What has been left unsaid?” Everyone would then wait until the patient found the words and said what had been unsaid. Sometimes the villagers would wait for days. Remarkably their cure rate was 98 percent.
