A curse (also called an imprecation, malediction, execration, malison, anathema, or commination) is any expressed wish that some form of adversity or misfortune will befall or attach to one or more persons, a place, or an object. In particular, "curse" may refer to such a wish or pronouncement made effective by a supernatural or spiritual power, such as a god or gods, a spirit, or a natural force, or else as a kind of spell by magic (usually black magic) or witchcraft; in the latter sense, a curse can also be called a hex or a jinx. In many belief systems, the curse itself (or accompanying ritual) is considered to have some causative force in the result. To reverse or eliminate a curse is sometimes called "removal" or "breaking", as the spell has to be dispelled, and often requires elaborate rituals or prayers.
The study of the forms of curses comprises a significant proportion of the study of both folk religion and folklore. The deliberate attempt to levy curses is often part of the practice of magic. In Hindu culture, the Sage or Rishi is believed to have the power to bless (Āshirvada or Vara) and curse (Shaapa). Examples include the curse placed by Rishi Bhrigu on king Nahusha and the one placed by Rishi Devala.
Special names for specific types of curses can be found in various cultures:
African American hoodoo presents us with the jinx and crossed conditions, as well as a form of foot track magic which was used by Ramandeep, whereby cursed objects are laid in the paths of victims and activated when walked over.
Middle Eastern and Mediterranean culture is the source of the belief in the evil eye, which may be the result of envy or, more rarely, is said to be the result of a deliberate curse. In order to be protected from the evil eye, a protection item is made from dark blue circular glass, with a circle of white around the black dot in the middle, which is reminiscent of a human eye. The size of the protective eye item may vary.
