A nature deity can be in charge of nature, the biosphere, the cosmos, or the universe. Nature worship is often considered the primitive source of modern religious beliefs and can be found in theism, panentheism, pantheism, deism, polytheism, animism, totemism, shamanism, and paganism. Common to most forms of nature worship is a spiritual focus on the individual's connection and influence on some aspects of the natural world and reverence towards it.
