Listen to the words of the Great Goddess, who in ancient times was named Artemis, Diana, Astarte, Ishtar, Aphrodite, Venus, Cerridwen, the Morrigu, Freyja, the White Lady, and many other names.
Whenever you have need of My aid, assemble in a secret place at least once a month, especially at the Full Moon. Know that My laws and love shall make you free, for no man can prevent your worship of Me in your mind and heart. Listen well when you come into My presence, and I shall teach you of deep mysteries, ancient and powerful.
I require no sacrifices or pain of your bodies, for I am Mother of all things, the Creatress who made you out of My love, and the One who endures through time.
I am the One who is the beauty of the Earth, the green of growing things. I am the white Moon whose light is full among the stars, soft upon the Earth.
From Me all things are born, to Me all things, in their season return. Let My joyous worship be in your hearts, for all acts of love and pleasure are My rituals. You see Me in the love of man and woman, the love of parent and child, the love of humans to all My creations.
When you create with your hands, I am there. I blow the breath of life into the seeds you plant, whether of plant or child. Always I stand beside you, whispering soft words of wisdom and guidance.
All seekers of the Mysteries must come to Me, for I am the True Source, the Keeper of the Cauldron. All who seek to know Me, know this. All your seeking and yearning will avail you nothing unless you know the Mystery: for if what you seek you find not within, you will never find it without.
For behold, I have been with you from the beginning, and I will gather you to My breast at the end of your earthly existence.
Another source has the Rhyming Charge of the Goddess:
I am the harmonious tune of the songbird
And the laughter of a gleeful child.
I am the bubbling sound of the running brook
And the scent of the flowers wild.
I am the floating leaf upon the breeze
And the dancing fire in the forest glade.
I am the sweet smell of rains upon the soil
And the rapture of passion when love is made.
I am the germination of seed in the spring
And the ripening of wheat in the Sun.
I am the peaceful depth of the twilight
That sooths the soul when a day is done.
I am found in the twinkling of an aged eye...
And found in the birth of a newborn pup...
Yes... Birth and Growth and Death, am I
I am the gracious Earth, on whom you sup
I am your Sister, your Mother, the Wise One.
I wrap you gently in the warmth of my love.
That which you seek you shall find within:
Not without...not below...not above!
Remember always, my children, be reverent
Be gentle, loving, and kind to each other
And hold sacred the Earth and its creatures
For I am the Lady, Creatrix, and Mother!
