A mudra is a symbolic or ritual gesture in Hinduism and Buddhism. While some mudras involve the entire body, most are performed with the hands and fingers. A mudra is a spiritual gesture and an energetic seal of authenticity employed in the iconography and spiritual practice of Indian traditions, among others.

In yoga, mudras are used in conjunction with pranayama (yogic breathing exercises), generally while seated in Vajrasana pose, to stimulate different parts of the body involved with breathing and to affect the flow of prana in the body.
A brain research paper published in the National Academy of Sciences in November 2009, demonstrated that hand gestures stimulate the same regions of the brain as language.
