“Yei” (pronounced “yay”) is the Navajo name for the benevolent supernatural beings who bring their healing power to medicinal ceremonies still performed today. In fact, they were first portrayed in traditional sandpainting designs created for these ceremonies, but the modern Yei rug is more of a pictorial composition, showing a row of the front- facing stylized stick figures. Between the Yeis cornstalks, feathers and arrows may appear, and a Rainbow Guardian often surrounds and protects the figures on three sides, indicating the sandpainting roots of this particular style.
“Yei-be-chai” is the name of the masked human dancer participating in the actual healing ceremony and impersonating the Yei. The Yei-be-chai rug portrays a line of dancers, usually shown from the side and often with one foot raised as though in a synchronized dancing motion. The patient for whom the ceremony is being held may be shown facing the procession. The medicine man and “Talking God” often lead the way, and a clown is often shown at the end of the line.
