It is unrelated to the fishing.... but it is kind of related to the fishing.... it is the burning of sacred herbs (white sage, cedar etc ) practiced by Indigenous peoples ( Anishinaabe) here in Canada and USA
My ancestors are Ojibwe (Chippewa) and we do the smudge to celebrate the Summer Solstice and to give thanks to the Great Spirit ..... Gitchee Manitou.
I see, had no idea!
What a nice gesture of celebrating the summer Solstice and being thankful. Will do some reading on it.
