Mudra

In Indian religions, a mudra (Sanskrit, literally "seal") is a gesture made with the hand or fingers. Along with "asanas" (body postures), they are used in yoga. Each mudra has a meaning. They are a central part of Hindu iconography. Mudras are also used in Buddhism. There are hand gestures 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 fear.
