Among other things, he is said to have done at Gokul, he lifted Mount Govardhan to save the people of Gokul from a storm. He also tamed Kalia, a giant snake that lived in the Yamuna river and terrorised the people of Gokul. While still in his teens, Krishna came to Mathura where King Kansa had organised a wrestling tournament. Krishna participated in it and after defeating all the contestants, he challenged Kansa to a wrestling bout. The evil Kansa’s time was up: Krishna defeated him and killed him. The people of Mathura were relieved.
Another major event in Krishna’s later life was that he functioned as an adviser to the Pandavas and during the Mahabharata war between the Pandavas and Kauravas he was Arjuna’s (one of the five Pandava brothers) charioteer. The original recitation of the Bhagvad Geeta (Song of the Blessed Lord) is accredited to him.
