Skull candles are used to influence the mind, call upon death, used in ancestor work, and necromancy. One way to use Skull candles to control someone's thoughts is to take Domination Oil and 7 Iron Nails. Carve the name of the person into the skull, and fumigate in Tobacco. Nail a petition paper to the skill candle, anointing each nail with Domination Oil. You can burn this or keep it in a box or jar and work on it continuously.
This working can be altered of course with other formulas, including Follow Me Boy Oil, Follow Me Girl Oil, Come To Me Love, Crossing Oil, and many others.
