All Pagan movements place great emphasis on the divinity of nature as a primary source of divine will, and on humanity's membership of the natural world, bound in kinship to all life and the Earth itself. The animistic aspects of Pagan theology assert that all things have a soul - not just humans or organic life - so this bond is held with mountains and rivers as well as trees and wild animals. As a result, Pagans believe the essence of their spirituality is both ancient and timeless, regardless of the age of specific religious movements. Places of natural beauty are therefore treated as sacred and ideal for ritual, like the nemetons of the ancient Celts.
