Take a shallow bowl of water, and sit down on the grass in a place where the full Moon shines. Set the bowl down in front of you, and catch the reflection of the Moon in the water, saying three times:
Aradia, Aradia. I implore thee,
Please to grant my wish for me.
By the powers of Moon and sea,
As my will, so mote it be!
Then gently skim your hand over the surface of the water, capturing the moonsilver in your hand. Before the water settles, empty the bowl onto the Earth, and return home. Do not look back at the moon after you've caught the moonsilver, or you'll break the spell!
