Original Narmadeshwar Shivalinga and Narmada Shivalinga.
 
The Narmadeshwar Shivalinga is an object of veneration for devotees of Lord Shiva. It is believed to embody the divine presence of Lord Shiva himself and is therefore considered sacred and potent. The natural markings and patterns on the cylindrical or elliptical stone are unique and often exhibit a smooth and polished surface, which is the result of years of erosion and tumbling in the river currents. The Shivalingas are sourced from the Narmada River, which is one of the seven holy rivers of India. The stones are naturally formed in the riverbed from a specific type of stone called cryptocrystalline quartz, also known as Narmadeshwar stone.
 
Devotees often perform elaborate rituals and ceremonies to worship the Narmadeshwar Shivalinga, offering flowers, water, milk, and other sacred substances. The act of worshipping the Shivalinga is believed to invoke the divine presence of Lord Shiva and bring about auspiciousness and blessings.
