Gichi-Manidoo, the great mystery, stands at the source, and beneath that the world is understood as populated by manidoog, powers with their own agency, attached to directions, waters, weather, animals and places. The relationship a person has with them is individual and is established rather than assumed, most notably through fasting and through what is received in that fasting.
The world is not governed from a throne. There is no divine king, no council of gods with portfolios, and no succession between generations of deities. What organises the tradition instead is relationship and reciprocity: with the manidoog, with the clan, with the beings whose lives sustain human life, and with the land itself.
Nanabozho occupies a position that has no clean equivalent in the pantheons of the Old World. He is at once the being through whom much of the present world came to be arranged and a figure whose appetites and misjudgements make him funny, and the tradition holds both without embarrassment.
The Midewiwin, the medicine lodge, is a graded institution with its own teachings and its own record, entered by invitation and instruction over years.
Anishinaabe religion is living, held by nations across the Great Lakes, and is listed by this atlas as restricted. The atlas states that the lodge exists, what kind of institution it is, and that its material is not public.
