The Mother Before Creation is walking in the outer darkness. Her steps touch nothing. Her steps touch Herself, who is all things. She uses space as a mirror. This mirror is known as the Mirror of Darkness. In it, the Mother Before Creation is as vast as a starless universe, like sleep without dreams, like sleep in which all dreams reside. She draws the image from the mirror into space and calls her "Miriel", which means "Beautiful One from God". Each is virgin: unspoiled sexuality in all its freshness. Yet old beyond time, each kissing the other with all the ripeness and experience of a dying courtesan. They make love, each desiring the other as much as they desire the Self.

Then Miriel moves away from the Mother Before Creation so dark emptiness lightens to cobalt blue as she becomes Dian-Y-Glas, The Blue God. The Great Mother says to Him, "They shall never take you from me. Whatever from you take, because you are my word, my hammer, and my seal, you shall return to me in your present form. And this our love shall be forever. And through our sexual union all things shall be created and are created, all things which were and are not, and are yet to be.

Here are some of Francesca's comments on the myth in her book Be a Goddess!:

One mystery revealed in this myth is the true nature of darkness, embodied in the universe as the Mother's mirror. In the Christian creation myth, God looked into the darkness, into the void, and decided to make something to fill it. And henceforth He remained separate from that which He created, outside of nature and humanity. The theological implication is that God is too good to be a part of nature, and thinks the material world evil.

How much more sense it makes that the Goddess saw Herself as that void, that darkness, and from that loving, vital, dark womb all things were created. Instead of condemning the material world, She not only saw it as Herself, but loved and embraced it, just as She embraces us whenever we call on Her. The belief that the Goddess is within us and all of nature is called immanence, andimplies that nature is good and sacred

...Darkness... is not evil; it is the darkness of spring nights when lovers court, of the rich soil from which our food is grown. It is the darkness that a child finds when snuggled under the covers at night while a mother whispers tender words of loving reassurance.

The Goddess's dark immanence also makes sense in terms of physics: past the lighted atmosphere of earth is mostly darkness. The cosmos is not, as some would have it, a balance of light and dark, but mostly darkness. Furthermore, most of an atom is empty space; there is very little matter to the material world. Existence consists mostly of the emptiness between the particles of the atom... So most of reality is dark and empty. But just as the dark is not evil, so this is not an evil emptiness. This emptiness is the Mother Herself, replete with Her love and fecundity. Sweet mirror of darkness! O luminous darkness.

Darkness is not only our shadow, but also the mirror through which we find our essential and beautiful selves... When in darkness, it is crucial that we not hide in it, but face its gift and its challenge. Especialy there, we need to be true and authentic! O luminous darkness.
