Yoga Mudras

A mudrā (Sanskrit: "seal") is a symbolic or ritual gesture in Hinduism and Buddhism. While some mudrās involve the entire body, most are performed with the hands and fingers.
Mudrā (Sanskrit) is "spiritual gesture" and energetic "seal of authenticity" employed in the iconography and spiritual practice of Indian religions and Taoism.
Mudrās are arm, hand and body positions used in the traditions of Hinduism and Buddhism. The great Buddha knew the use of mudrās and is often depicted using these ritual gestures.
Various Kung Fu forms contain positions identical to these mudrās. 108 mudras are used in regular Tantric rituals. Mudras are also used in Indian Classical Dance. There are over 200 mudras in bharatanatyam and over 250 in mohiniattam.
