Personal concerns are anything that carries the DNA of a person such as hair, nails, blood, urine, semen, sweat, clothing and anything else you might be able to get your hands on (although you might not want to get your hands on any of it). Personal concerns are used for a variety of reasons in hoodoo work. Unlike other forms of magic, they aren't just used as a sympathetic connection, their use is much more varied and direct.
There are two main ways love can be worked with from a spiritual/magical perspective. One path of drawing love is what I call “good” and the other path is what I call “bad”.
