Place a jewel, that you regularly carry on you, in a cup of spring water a day before the full moon. The following day, on the evening of the full moon, stir the water three times with your finger in a clockwise motion. Take the cup in your hands and move the cup in a clockwise, circular, stirring motion three times.
Then, repeat these words aloud:
Oh Light of the Moon,
Keep me from harm.
Raise the cup towards the sky and drink the water. Remove the jewel from the cup.
You must carry it on your person till the next full moon in order to ensure your protection.
Repeat this ritual every month to benefit from its influence.
