Govardhana is a 8km long hill located near the town of Vrindavana in the Mathura district of Uttar Pradesh. It is believed that thousands of years ago, Lord Krishna lifted up this hill and held it over His head with his little finger for 7 days to protect the inhabitants of the town from the wrath of rain God Indra.
It was customary for the people of Vrindavan to pay annuual tribute and obeisance to Indra for bringing them good vegetation and greenery, thus providing them and their cattle with abundant food. When Krishna saw the preparation for this annual event, he debated with his father and the villagers whether this was indeed necessary. He felt that all human beings should merely do their 'dharma' to the best of their ability and not pray or conduct sacrifices for natural phenomenon. He told them to worship the Govardhan mountain as it was His own manifestation.
