Inside, First Man lay with his head to the East, and First Woman lay with her head to the West. Their thoughts mingled, and those thoughts were sacred. They began to plan for the time that was to come, and how people would live on the earth. Great Coyote-Who-Was-Formed-in-the-Water came in to help them plan. Together, they planned that there should be a sun, a moon, and day and night. They decided to keep the other Coyote, First Angry, away from their planning, because it was he who had brought unhappiness.
First Man, First Woman, and Great-Coyote-Who-Was-Formed-in-the-Water covered the floor of the hogan with a perfect buckskin. On the buckskin the placed a perfect round turquoise, larger than the height of a man. Below the turquoise they placed a great perfect white shell. At that moment the Coyote Áłtsé Hashké, First Angry, came and asked them what they were doing. "Nothing," they said. "So I see," he said. And he went away.
First Man went looking for Haashchʼééshzhiní, The Black Yéʼii, known as the Fire God. First Man found him in a place where there was fire under the earth, and called to him. He returned to the first hogan with First Man. First Man and First Woman also summoned the other three Holy People, Water Sprinkler, House God, and Talking God. Together, they told Turquoise Boy and White Shell Girl that they were creating the sun and the moon. They asked Turquoise Boy if he would become the sun, and they asked White Shell Girl if she would become the moon. Again, the Coyote named First Angry came by and asked them what they were doing. "Nothing," they said. "So I see," he said, and he went away.
First Man, First Woman, Great Coyote, and the Holy People planned that there would be 12 months. With each month, the moon would pass from dark to light, and the sun would move to a different path in the sky. White Shell Girl was given a whistle made from the Female Reed, with 12 holes in it. Each time she completed her cycle she would blow on the whistle, and a new month would begin. The first month was named Ghąąjįʼ, Back-to-Back, or Parting of the Seasons. Today it is called October. The second month was named Níłchʼitsʼósí, Time of Slender Winds. The third month was Níłchʼitsoh, Great Wind. It is the time to begin to tell the sacred stories. The fourth month, January, was Yas Niłtʼees, Crusted Snow. This is the month of many ceremonies, and the time for sacred stories. February, the fifth month, is Atsá Biyáázh, Baby Eagle. After this month, sacred stories must not be told to the young people. The sixth month, Wóózhchʼį́į́d, is the month of Sudden Spring Storms. Ceremonies are held to bless the fields before seeds are planted. The seventh month was Tʼą́ą́chil, Little Leaves. May, Tʼą́ą́tsoh, was the eighth month. Finally they planned Yaʼiishjááshchilí, When-Few-Seeds-Ripen, Jáátsoh, Great Seed Ripening, Biniʼantʼą́ą́tsʼózí, Little Ripening, and finally September, Biniʼantʼą́ą́tsoh, Harvest Time, when foods are stored for the winter.
Again, the Coyote named First Angry came by and asked what they were doing. "Nothing," they said. "So I see," he said, and he went away.
Fire God, the Black Yéʼii, used his fire to heat the turqoise on the buckskin until it became red hot. Then they asked Turquoise Boy to enter the glowing turquoise. "If I do that, I must be paid with the lives of the people of the earth, all the human beings, the animals which have four legs, the birds and insects of the air, the fishes and all the people under the water." And then the White Shell Girl repeated the same thing. First Woman, First Man, Great Coyote, and the Holy People all agreed. Then Turquoise Boy entered the glowing Turquoise. First Man used his crystal to heat the White Shell, and White Shell Girl entered the White Shell. Four circles were made around the inside of the hogan to complete the ceremony. In this way, Turquoise Boy became the sun, Jóhonaaʼéí, The One Who Rules the Day. And White Shell Girl became the moon, Tłʼéhonaaʼéí, The One Who Rules the Night. Níłchʼi Haʼaʼaahdę́ęʼgo, the East Wind, asked to carry the newly formed sun to his land so that it could begin its journey there.
The Coyote named First Angry appeared again. He said, "I know you have been planning great things. I demand to know why I was not included in the planning." First Man and First Woman said nothing. Coyote said, "You believe that I spoiled your living in the lower worlds, but it is not true. Now I will spoil your plans. The path of the sun and the path of the moon will not return to their beginning after 12 months. The twelve months of the sun will be 13 months of the moon. Sometimes frost will come early, and sometimes it will remain late. Sometimes the rains will not come, and you will have to summon the baby of the Big Water Creature to bring water." And he left them.
