Basic Full Moon

First cast a Circle. The Circle should be fully cast, as major acts of Magick that are required by a full moon ritual, need a Witch's total concentration. It is very difficult to maintain a lesser Circle during major Magicks and could be dangerous to the Witch. Once the Circle is cast, kneel before your alter looking up at the moon and say;

Lady Moon bright and serene,
Shining with the bounty of the Mother,
Look down on us your Children of the Earth.
Come, light of the Goddess,
Fill us with your power.
Lend us your blessings,
Let your light surround us.
Impart to us your light and blessing.
Your love and grace, surround us.
Surround us Goddess,
Surround us with your love.

Once the moon's energy has been called down, a Witch must direct the granted energy. Sometimes, there will be no direction but only meditation. The energy is then released with the undoing of the Circle into the environment. A spell or series of spells can also direct or use up the granted energy. A request can also be made of the Goddess. She may then choose to use the energy you have been granted, for the stated purpose. Say:

Power blessed to me by the Goddess,
rise in me for healing,
to replenish and renew my being.
Power blessed to me by the Goddess,
Surround me with strength.
By the power of the Goddess,
So mote it be.

Keep the request formal if you want. A more personal prayer will also be heard if you choose not to set your request into words. If there are others within the Circle who have taken part in the ritual, have them also make their own request. I have also heard of group requests that work just as well. As with many other strong Magicks or major rituals, the rite must be closed. Say:

Goddess and Spirits,
You have heard our voices,
and our Craft has been completed.
Depart with our thanks and our love,
as we eat these cakes to replenish our bodies,
and this water which shall cleans our souls.
By the power of the Goddess and Spirits,
This Circle is undone but not broken,
So mote it be.

Variations on calling down the moon and working with the given energy are all over the internet. There is no version that is the 'correct' version. The correct version, is the version that makes you feel good. Don't hesitate to make your own or adapt an existing ritual.
