Gardner's explanation aside, individual interpretations of the exact natures of the gods differ significantly, since priests and priestesses develop their own relationships with the gods through intense personal work and revelation. Many have a duotheistic conception of deity as a Goddess (of Moon, Earth and sea) and a God (of forest, hunting and the animal realm). This concept is often extended into a kind of polytheism by the belief that the gods and goddesses of all cultures are aspects of this pair (or of the Goddess alone). Others hold the various gods and goddesses to be separate and distinct. Janet Farrar and Gavin Bone have observed that Wicca is becoming more polytheistic as it matures, and embracing a more traditional pagan worldview.
