Light a white candle and focus on the person you wish to speak to. Grab two small papers and write 'YES' on one and 'NO' on the other. Underneath the words sketch a pentagram. Place the papers literally as close as you can fit next to the candle. Add salt to the melted candle wax to bind the spirit to the candle. Then, ask if a spirit is with us right now. Follow the flame and if it leans to the yes, you know something's around. Continue asking questions and follow the signs to know you are speaking with a spirit such as odd candle position, rippling, and a downward thrust. Snuff out the candle afterward.
