However, that Divinity is more than the human mind can encompass or experience. So the idea of divinity is broken down into a few or many mind-sized pieces. These pieces are conceived of in many forms. One of the primary forms Divinity takes for us is the Goddess, the Divine feminine. The Moon, the Sea, and the Earth can all be personified as Goddesses.
Some witches stop there.
Other witches include the Divine male, the God. Our God is not limited to the Father aspect, though there are Divine Fathers. Apollo, Cernunnos, Osiris, Dionysos, Odin Pan Freyr, Adonis, Tammuz, and many others. Nobody has the answer, nor do we pretend to. Deities may be archetypes, they may be nature spirits, they may be forces outside our ken.
