Today in modern pop culture, this hand symbol is associated with rock music and the satanic sign of the horned devil. However, this gesture in fact has an incredible amount of different meanings to different cultures, eras and regions.
For example, in Hinduism the hand gesture is known as the "Apana yogic mudra." In Indian classical dance forms, the hand gesture symbolises the Lion. In Buddhism, it is seen as a protective gesture against evil spirits, very commonly used by Gautama Buddha as "Karana Mudra" which is synonymous with expulsion of demons and removal of obstacles like sickness or negative thoughts.
