Kalyanasundara (, literally "beautiful marriage"), also spelt as Kalyansundar and Kalyana Sundara, and known as Kalyanasundara-murti ("icon of the beautiful marriage"), Vaivahika-murti (वैवाहिक-मूर्ति, "nuptial icon") and Panigrahana-murti ("icon related to panigrahana ritual"), is the iconographical depiction of the wedding of the Hindu deities Shiva and Parvati. The couple are often depicted performing the panigrahana ("accepting the hand") ritual of a Hindu wedding, where the groom accepts the bride by taking her right hand in his.
The couple, depicted in the centre, are accompanied by a host of divinities and other celestial beings. The god Vishnu and his wife Lakshmi are often pictured as giving away the bride to Shiva. The god Brahma is shown as the officiating priest.
The Kalyanasundara icon is not the object of popular worship and is usually used only in the celebrations of the divine marriage in annual temple festivals. However, Kalyanasundara scenes are found across India in caves, sculptures and on temple walls.
