This is a spell to attract the one you desire, though you must at least talk to them and know their full name.
Casting Instructions for ‘Think About Me’
Go outside on a Friday night and set up your alter. Cast a circle and make sure your alter is at the north edge of your circle. Call the Elemental Guardians. It is optional to smudge your circle, I just did it for protection. Engrave your desired ones name into the candle. Before you light it, chant this while the candle is bathed in the moons rays: Diana, Goddess of love, I ask that you hear me. Please let (desired one) Send love towards me. So mote it be. Then, light the candle and say: May you think about me day and night, (desired one). Now kiss the candle while its lit. Stare into the flame and visualize you and the one you love together, in love, for about 30 seconds. Let the candle burn out.
