Human religious belief is animistic totemism, similar to the beliefs of the Plains Indians of North America. The world is a dichotomy of Nature and Man, and each has a place within the other. Man must learn from nature and live within its rules, but at the same time nature gives way to the creativity and ingenuity of Man. The two aspects dance with one another, and harmony is achieved through balance. These two aspects are personified in the two types of holy men in human culture, the Skald and the Shaman.
