diyin yá naalʼaʼí-- meaning a supernatural messenger. It is not a Navajo concept. The word was made up after contact with Christians.
The Navajo word for Satan is "T’ááłá’íí," which translates to "the one who is evil" or "the evil one." In Navajo culture, this concept is often associated with malevolent spirits or forces rather than a singular figure like in some other religious traditions. The Navajo worldview encompasses a broader understanding of good and evil, focusing on harmony and balance in life.

There is a way. You have to have a voice recorder and ask the spirits questions and see if you caught any activity (you have to have an improved recorder).

Apparently, some people have come in contact with spirits.
Many American Indian tribes, including the Navajo, associate illness with evil spirits or malevolent forces. In Navajo culture, for example, it is believed that illness can result from the intrusion of harmful entities or imbalances in one's life. Healing practices often involve rituals, ceremonies, and the guidance of medicine men or women to restore harmony and dispel these negative influences.
Hogan is Navajo for medicine man. A medicine man in any Indian tribe is a shaman. Shamans use spiritual and medicinal herbs for healing and for interpreting signs to come. They also speak to spirits.
The first recorded contact between the Spanish and the Navajo was in 1583 near Mt Taylor. The Navajo name for the Spanish is Nakai, meaning "one who wanders around". The Spanish claimed but never really controlled the Navajo territory so there was not a lot of direct contact except in towns and Pueblos in what is now New Mexico. The Spanish had a large demand for Native American slaves. Navajo were captured by the Spanish or by other tribes and sold in markets in Santa Fe. Slaves were sent as far south as the silver mines in Mexico. Navajo women were in demand as weavers as well. By the late 1700s it is estimated that 66% of all Navajo had some family member who was a slave. The Navajo aided in the Pueblo Revolt of 1680 which killed 400 Spaniards. They gave shelter in 1692-3 to some of the Pueblo people when the Spanish returned. Quite a few Navajo clans come from this period of mixing.
