Central to Navajo beliefs is the Navajo creation narrative that includes this version:
Humans emerged from a series of previous worlds, where they existed as insects or animals. The deities, or Holy People, include Holy Supreme Wind, who gave life to all the other Holy People, and Changing Woman, who taught the people how to live.
She married the Sun and her twin sons, Monster Slayer and Born of Water, used lightning bolts to slay the monsters who were killing the new Earth People. Talking God taught the people how to make the first hogan, where the people first met to arrange their world.
They named the four sacred mountains that became the boundaries of their homeland: San Francisco Peaks in the west, Mt. Blanco in the east, Mt. Taylor in the south and Mt. Hesperus in the north.
Then the Holy People put the sun and moon in the sky and were carefully arranging the stars. But Coyote, the Trickster, grew impatient and took the blanket containing the stars and flung the remaining stars into the sky.
The Holy People also created the four original clans, and Changing Woman created four more clans to keep her company when she visited her husband the Sun every evening. They traveled from the west and joined the other clans already living at Dinetah.
The backbone of the Navajo ceremonial system is the Blessingway ceremony, through which a medicine man asks the Holy People to return peace, beauty, harmony and all good things, which the Diné collectively call Hózhó , a complex wellness philosophy and belief system comprised of principles that should guide one's thoughts, actions, behaviors, and speech.
Hózhó teaches that respectful thought, speech, and behavior should be nurtured and relationships in life, including those with the whole of creation in the universe, should be supportive and positive.
