Indic religion
In Hinduism, a mudra (Sanskrit, literally "seal") is a symbolic gesture made with the hand or fingers. Along with asanas (postures), they are employed in yoga meditation practice. Each mudra has a specific meaning, and they are a central part of Hindu iconography. With the onset of Buddhism, many mudra practices were absorbed into the culture. Common hand gestures are to be seen in both Hindu and Buddhist iconography. An example would be the outward-facing open palm known as Abhay (without fear) mudra, a gesture meant to dispel the fear of the devotee.
