It is said that whenever lord Vishnu has taken avtar lord Shiva use to keep a track of his welfare because of his love towards lord Vishnu.
Just as the Ganges is the best river among all rivers, similarly among all gods Lord Vishnu is the best. Just as Lord Siva is the best devotee among all the Lord’s devotees.
When Lord Vishnu took incarnation as Krishna, Lord Shiva goes to Gokul for a glimpse of Child –Krishna ( just like he went to Ayodhya when Ramji took incarnation ) .
Govardhan Puja, also called Annakut is celebrated as the day Krishna defeated Indra. It is the fourth day of Diwali, the Hindu festival of lights.
‘Govardhan‘, a small hillock situated at ‘Braj’, holds special significance for the Hindus. According the revered Hindu scripture ‘Vishnu Purana’, Lord Krishna once asked the people of Gokul to worship Govardhan Parvat for rain, instead of Lord Indra. Krishna told the people of Gokul that, it was the mountains and hill state bring all the rain to earth and not Lord Indra, whom people used to think, bestowed rains on earth. When people started worshipping the mountain, infuriated Indra showered heavy rains upon Gokul. To save the lives of people from the consequent flood, Krishna lifted the great Govardhan Parvat (hillock) on his little finger and offered shelter to the people of Gokul until the rains abated.
