It is an acknowledgment, central to the cultures of Native American peoples, that we and all things share in Creation:people, birds, animals, plants, trees, rocks, rivers.
"In olden days the Indians lived peacefully with all animals. Even the buffalo would often wander into the camp of the Lakota and eat the grass that grew within the circle of the village. They would usually come during the night and when the Lakota awoke in the morning there would be the buffalo. When the smoke began to rise from the tipis and the people began to stir about, the buffalo would move away."
