This series of spells and rituals to find job, work by concentrating energies around you (forming a kind of aura) so that it can be perceived as more competent by your current boss or a future employer, and might have a good image of you or the person on which the spell is done.
These spells can not be reversed, do not last long, and it there is usually no side effects or negative consequences if used incorrectly. It can be that you've already tried other ritual or prayer to get work, or that you don't already know to do to find work. If this is your case, I recommend you use these spells to find work. Don't be afraid to try them all, because they don't last long, and activate a ritual at the same time as another should not bring any problem in any case enhance the effect.
