The singular piece of literature that we have in Wicca, it was written by Doreen Valiente, who was Gerald Gardner's high priestess, and is an incredibly beautiful piece of poetry. It is used for drawing down the moon for a priestess when she is going into a trance and calling the presence of The Goddess into her and speaking then with the voice of The Goddess and seeing with her eyes, and as we say, kissing with her lips.
It draws upon a rich array of sacred texts. There are elements from the Egyptian. There is a tremendous amount that comes from my great personal favorite from The Gospel of Aradia, which was retrieved by Charles Godfrey Leland, who was an American folklorist and early anthropologist who spent a long time in Italy, particularly in Florence, and had an informant by the name of Maddalena, who has in fact now been proven to have existed, and she shared with him a lot of the folklore and rituals and magic of La Vecchia Religione, the old religion, the pre-Christian religion of Italy. And so, a part of the charge comes from that.
It's incredibly beautiful, and it's a summoning of all those who want to learn the Mysteries of the Universe. It expresses the divine as embodied in nature, in the moon and the Earth, and in each of us. It speaks about the polarity of human experience of joy and suffering and courage and compassion and strength and mercy, and all of these things rolled into one, as the journey of our souls in pursuit of the sacred. And if you haven't read it, you should.
