Navajo legend tells us that the Dineh had to pass through three different worlds before emerging into the present world - the Fourth World or Glittering World. So, the Holy People put four sacred mountains in four different directions. Mt. Blanca in the east. Mt. Taylor in the south, San Francisco Peaks in the west, and Mt. Hesperus in the north, thus creating the boundaries of Navajoland. Centuries ago, the Navajo people were taught by the Holy People to live in harmony with Mother Earth and how to conduct their many activities of everyday life. The Dineh believe there are two classes of beings: the Earth People and the Holy People. The earth People are ordinary mortals, while the Holy People are spiritual beings that cannot be seen. Holy People are believed to aid or harm Earth People.
When disorder evolves in a Navajo's life, such as illness, herbs, medicinemen (diagnosticians), prayers, songs and ceremonies are used to help cure the ailment. Some tribal members prefer modern day hospitals on the Navajo Reservation; some seek the assistance of a traditional Navajo medicineman, some combine both methods. Navajos believe that a medicineman is a uniquely qualified individual bestowed with supernatural powers to diagnose a person's problem and to heal or cure illnesses. The Dineh believe they are sustained as a nation because of their enduring faith in the Great Spirit. And because of their strong spirituality, the Navajo people believe they will continue to survive as an Indian nation forever.
