Lord Nandi, the sacred bull, is the vahana (vehicle) of Lord Shiva and also the gatekeeper of Kailash. He symbolizes strength, devotion, loyalty, and service. Devotees believe that prayers whispered in Nandi’s ears are directly conveyed to Lord Shiva. Nandi’s form inspires discipline, faith, and a life of devotion. His association with Shiva represents the harmony of power and purity in spiritual life.
