One day sri Krishna’s grandson Aniruddha(son of Pradhyumna) was relaxing on a cot and suddenly he disappeared. No oneknew what had happened to him. The Yadavas became worried. Sage Narada appeared before Sri Krishna and told him whereAniruddha was and what his condition was. This way he helped the Yadavas to find one of their dear ones. In fact, hewas taken to Shonitapura, the capital of demon king Banasura by the help of some witchcraft. The youngman saw Banasura’sdaughter Usha Devi and fell in love with her. Banasura was furious and he tied Aniruddha up with nagapasha. The Yadavasasked Sri Krishna to go Shontipura and get back Aniruddha. Sri Krishna collected a huge army and marched towardsBanasura’s capital. He laid seige on the city and defeated Banasura and brought back his grandson along with his fiancee,Usha Devi. Sri Krishna had to fight with Parashiva, who came to the help of Banasura. Narada, by revealing thewhereabouts of Aniruddha, helped Sri Krishna defeat Banasura. The arrogant asura was subdued and Sri Krishna’s greatbravery was revealed to the world.
