From the Museum site: Portrayed in an unusual dancing pose, the cosmic Shiva is shown with five heads and eighteen arms that bear weapons and ritual instruments. Shiva has a hermit's piled-up hair on his upper heads, in front of which a crescent moon appears. The wavy white line at the right is the Ganges River, which descends from Shiva's hair when he is residing in his mountain hideaway.
