The marriage of Shiva and Parvathi was to be celebrated on mount Kailasa. All the people all over the world started traveling towards mount Kailasa. Due to the heavy burden on the northern side, the world started tilting towards the north. To correct this Lord Shiva requested sage Agsthya to go and live in the South of India. Agasthya obeyed the orders of Lord Shiva and reached the south. The entire south India was extremely dry at that time. Lord Shiva had sent some sacred waters of Ganga along with Agasthya, which Sage Agasthya was preserving very carefully in his pot. One day when was asleep, Ganapathi took the form of a crow and toppled Agasthya’s pot. From the Ganga started spreading in to a river. This river was called kaveri – She who was spread by a crow.
