How did a Mayan diviner in Guatemala use eggs to diagnose illness?

In the context of divination, a contemporary Mayan diviner in Guatemala uses eggs as part of an interpretive diagnostic process to identify the nature and origin of an illness.1

The procedure involves the following steps:

• Extraction: The diviner carefully passes a number of eggs over the patient’s body, a practice intended to draw the essence of the affliction into the eggs.1
• Collection: The intact contents of the eggs are collected into a receptacle filled with water.1
• Interpretation: The diviner moves to a darkened area to examine the contents of the receptacle. By reading the signs manifested within the eggs, the diviner provides a recitation that interprets the specific cause and nature of the patient's disease.1

This method is classified as interpretive divination, as it relies on a combination of established procedure and the diviner's personal insight.1
