I totally agree with Marcel. Psychologically...It is most correct.
In occult circles, there is a simple drawing one does in the air with ones finger. One also uses this while astral travelling to banish any evil, or to cleanse a temple before a ritual.
If one believes in any occult workings, one may use this simple drawing while saying.."negative forces OUT, positive Forces IN!! Of course, one must believe in its Power to achieve the result..of banishing any curses, hexes etc..Of course, this is psychologically induced..and the result, if one believes in its power.. is the same as Marcel's..to remove the fear completely...To know if one is cursed/hexed? IT is the fear they are experiencing, as Marcel stated.
