Hold the item above your head. Take a moment to feel the swirls of energy around you. You should be able to feel them tug at you like a current in a river.
In a clear voice, say:
Let the sacred powers of the universe unite and fill this (item name) with energy. By the Moon, the Sun, the Earth and the Stars I charge this (item name) to do my will. So Mote it Be! Close your eyes and envision an energy bolt striking the item and causing it to glow. You should feel a subtle vibration while you hold the item.
Your tool is now charged.
