According to BhaktiMarg, the difference between Shivling and Shivmurti lies in the way Lord Shiva is represented in Hindu worship. A Shivling symbolizes the formless and infinite cosmic energy of Lord Shiva, representing the eternal and universal nature of the divine beyond physical form. It is considered a spiritual symbol of creation, consciousness, and the limitless power of the universe
