Banalinga, a stone found in nature, in the bed of the Narmada river in Madhya Pradesh state, India, is an aniconic symbol of worship, based on either the scriptures or cultural traditions among the Hindus, particularly of the Shaivaites and Smartha Brahmins. Stones are ancient and connote divinity. It is a smooth cylindrical stone. Banalinga is also called the Svayambhu Linga: (Sanskrit) "Self-existent mark or sign of God", as it is discovered in nature and not carved or crafted by human hands.
