An elephant performed the ritual of bathing daily in the Gokarnam pond. It took water and lotus from the pond and performed pooja at a specific place. Tala and Kaada were the two who wanted to know what was happening. They struck at the tree with an axe and blood gushed out from the cut. They realised that they had struck at a Siva lingam and pleaded forgiveness. The blood that was gushing out turned to white milk. They heard a divine voice that instructed them to dress the wound with the leaves and fruits of the tree. They attained moksha by drinking the milk. Since the Sivan lingam had shown ways of healing, the Lord is known by the name Viadyanaatheeswarar. .
