To my mind the Charge of the Goddess written by Doreen Valiente is one of the most beautiful pieces of work in Wicca. It speaks to us in ways that touch us very deeply. That being said, it is also in a way very generic addressing a Goddess without a name or a face. And many of us have developed relationships with specific Deities over the years, God and Goddesses with whom we work closely and to whom we turn in need. Some of them don't match the images in the Charge of the Goddess.
So here's an exercise that a good friend has her students do in order to help them get more in touch with their specific Deities. Try re-writing the Charge using words and imagery that are specific to the God or Goddess with whom you identify most closely.
As an example, I have been working with Sekhmet for many years. Here is the Charge of Sekhmet that I wrote as my response to the exercise I mentioned.
The Charge of Sekhmet:
Listen to the words of the Sekhmet; She who of old was also called Beloved of Ra, Lady of Transformations, Opener of Ways, Shining One, and four thousand other names.
When you have need, come unto my temples and walk amongst the sacred columns. There shall I teach you the Mysteries and the ways of all magic. There shall I give unto you that which is hidden from those who do not seek in truth. I am the Way and I am the Key to the secret door. My paths are perilous and those who tread them do so in dread and joy. For I am the Creator and the Destroyer. I am the Weigher of Souls and I know all that lies in your heart. I will ask of you sacrifice, I shall demand of you truth, I shall strip you of all weakness and pretense. And I shall give unto you immortality.
Hear ye the words of Sekhmet; before whose wrath even the Gods tremble, whose light is the blazing sun, and whose arrows lay waste the foes of Pharaoh.
I who am the black earth, the Sun in its glory, and the miracle of the waters; I who bring passion and desire in the heart of man; I do call unto you. Arise and come to me. For I am the floods that bring life from the desert, and I am She who bears your soul to Ma'at at life's ending. I gave birth to the oldest Gods, and I was there when mankind was formed from the mud of the Nile. Let my worship be in the heart that trembles before me, for I am the Overcomer of All Enemies and my ways are open only to the pure in heart and the strong of spirit. Know that I am with you always, from your coming in until your going forth. And lo, I shall be beside you in the Boat of Millions of Years as your soul reaches the undying lands and joins me forever.
