There is no pan-indigenous language. Any language you might use that a certain first nation, Inuit or Métis person has used is from their community and from their society. For Inuit, this isn't Turtle Island, although we respect the first nations who describe the world in that way.
The complexity of indigenous people's world view in this country, first nations, Inuit and Métis, reflects that of any major ethnic group of people in terms of society and religion. When you talk about ceremony, when you talk about these things, they are for a specific portion of first nations, Inuit and Métis in this country. They are not for all. There is virtually no statement you can make that encompasses the religious or social beliefs of all indigenous peoples of the country at once. Refraining from those types of blanket statements gets you closer to the respect from all first nations, Inuit and Métis.
