You may use this only three times in between the new moons.
While gazing at the moon, repeat the following:
"Moon, moon, beautiful moon, brighter that any star, Goddess of light and love, Diana if it might be, pray bring fortune unto me".
A sign that the spell worked would be coins doubling in the purse or pocket, or seeing a hare before dawn.
Note: The spell won't work if done with evil intent.
