The dark powers emanate from the dark aspects of the Goddess and the God. This is the power of the Crone and the Lord of the Shadows; the Hag and the Hunter. The dark powers are more than just a personification of the negative influences in life, however, and the energy raised through the dark imagery of the Divine is very potent. As such, be careful what you do.
The Dark Goddess is manifested in mythology as various kinds of death crones, wise hags, devastation, war, disease and barrenness of the land. She is the Bone Mother who collects the skulls of the dead for the ossuary. In Irish mythology, Morrigan and Nemain would be considered Dark Goddesses in that they are associated with War and Death.
The Dark God is seen in mythology as the silent host to the dead in his underground realm of gray shadows and deep sleep, knowing of secrets and wise of the universe, death, war, destruction, gatherer of souls and harbinger of chaos. He is the Hunter, whose wild hunt, or raid, ingathers the energies of the soul.
There is sense to this ancient cosmology. Cults of ancient times focused on the dark aspects of the Divine so that their followers would move past their fear of mortality to seize upon the recognition of their eternal immortality.
In Irish mythology, Crom Cruach, and Donn would be considered “Dark Gods” or “Dark Powers” because Donn was the god of the dead Milsians. At death, Mannannan Mac Lyr carried the soul to Tech Dunn or the House of Donn. In texts like the Dinsenchus there is references to Crom being considered to be a dark god, contrasting a light god, in a way that is very similar to the Slavic god Czernobog.
As a power, the Dark Lord is the Chaos from which Order must evolve. Yet there is no ending to this cycle, Order resolves again as Chaos to be reborn as New Order. The Lord of Shadows as Death becomes the process of new life by gathering the energy of dying life, and the Passage into a new material form is through the Crone.
In the aspect of light, the god dies willingly by entering the ground to bring his vitality to crops that will be harvested to feed humanity. Through this selfless act, he revitalises the earth. He does this through the Crone. The marriage of Lugh in August, celebrated as Lughnasadh, is the start of the descent into Mother Earth. Once there, he is transformed into the son within the goddess. Hence, the pagan god is both Father and Son, which is yet another concept that Christianity absorbed from the pagans. The harvest comes, the seasons change, and the Mother becomes the Crone of Autumn and Winter, only to be transformed into Mother again at Winter Solstice with the rebirth of the Sun (her son, the god). See Also: Cernunnos, Green Man and Herne.
The womb-tomb is the domain of the Crone and is a place of great power. This is where the transformation takes place, with energies of death given repose and returned to form as the energies of life. When this power is confronted and recognised, there comes a freedom from fear, a new sense of independence and a recognition of personal responsibility. We are not judged in Death by the Lady and the Lord, but we are Self-judged. From the quietude of the realm, we move through her into new life. That is the balanced, pagan theme of the cauldron, the god of self-sacrifice and the resurrecting goddess. It is this power of the goddess that significantly differentiates the old and new religions.
Thus, in an historical sense, while the Dark Lord guides the chaos of social and cultural changes through the Crone into a new life, the Crone becomes not the terror of death, but the joyful passage to new vibrant societies through the death of the outmoded and stagnant ones. She is Fata Morgana, the Huntress Diana, Minerva, Cerridwen, Sati and Kali. He is Pluto, Hades, Cerunnos, Herne the Hunter, Set and Shiva. But the names may not convey the image needed by the practitioner unless you are able to move beyond the modern association of darkness as evil.
By accepting that the dark powers are in balance with the light powers, you are able to utilise the wholeness of the Power. The dichotomy of good and evil do not apply to what simply is. Energy can be drawn to the light or to the dark; thus death provides the soul’s passage to whichever realm the soul-energy has been drawn. Energy is always in motion, and flows back and forth between light and dark. What at one time is light energy turns and becomes dark energy. Through the practice of the Craft, the witch directs this energy for beneficial purpose. To do otherwise, is to inflict Self-harm.
To face the Underworld and the power of the dark aspect of the Divine is to understand that dark is part of the necessary blend of light and not something to fear. The unifying of the dark and the light within the individual offers wholeness and peace, which may then be transferred to external contacts.
