The Navajo Yeibichai (also spelled Yéî Be Chei or Yébîchai) refers to both a nine-day Navajo healing ceremony and the masked dancers who participate in its final night. The ceremony, also known as the Nightway, is a complex ritual performed to heal the sick and restore balance and harmony. The Yeibichai dancers, impersonating the Holy People (Yei), play a crucial role in this process by embodying the spiritual beings and their healing powers. Condition is excellent.
