According to the Scriptures, Govardhan Parvat used to provide fruits, flowers and food for the Brajvasis, cows and all other animals. Therefore, the natives of Braj started worshipping Govardhan Parvat instead of Indra Dev. Angered by this, Indradev caused severe rain in Mathura due to which the entire city started drowning. In such a situation, Shri Krishna lifted Govardhan Mountain on his finger to break down the arrogance of Indra Dev and to protect all the natives of Braj. Thereafter, all the Brajvasis took shelter under Govardhan Parvat for seven days. Seeing this, Indradev realised his mistake and apologised to Shri Krishna. Henceforth, along with the worship of Shri Krishna and Radha, it became a tradition to worship Govardhan Parvat in Mathura, especially on Govardhan Puja. There is tradition of Annakoot Bhog and Gau Seva on day of Govardhan Puja.
