I think it could be tying together ideologies/mythologies across specific cultures that are far from one another but actually hold similar myths-which lends support to the idea of universal truth across humanity by spontaneous development. Right when I saw it I read as a nod to the myth of the sacred hoop/medicine wheel (Sioux) that speaks on the interconnection of everything in the universe, old Celtic myth uses four directions as well to symbolize the connection of mind/body/soul/heart in tandem w elemental ideas.
