To rid yourself of feelings for an unrequited love.
Take a healthy orange and on one side carve your name and on the other the name of the one you love. Concentrate all your feelings for the person into their name as you hold it and visualize this person's face.
Put the orange in a private place in your home where you can see it at least once a day but others cannot. as you watch the orange rot away, so will the unrequited love for this person wither and die.
