Hold the riverstone firmly between your palms and visualize the riverstone building a shield of bright light around you. When the shield is complete, cup the stone in your palms, look at it and say:
By the power of light from dark I charge thee
To use thy shield to defend me.
Paint the runic symbol for eihwaz upon the stone. (Eihwaz means yew tree and was one of the most revered trees of Viking times. The symbol stood/stands for general protection, magickal empowerment, and psychic protection.)
Place the riverstone next to the candle and allow the candle to burn down.
Close the circle.
Let the paint dry overnight. Once dry the stone should be carried with you
