Best time : Full Moon
Fill your cauldron half full with water and drop a silver coin into it. Position the cauldron so that the light of the moon shines into the water. Gently sweep your hands just above the surface, symbolically gathering the moons silver.
Whilst doing this say:
"Lovely lady of the moon,
bring me your wealth right soon.
Fill my hands with silver and gold,
All you can give my purse can hold."
