"Damayanti was the Yadava princess of Vidarbha Kingdom. One day, a beautiful swan came to her and told her about Nala, king of Nishada. The swan was sent by Nala after hearing about her from it. After hearing about Nala, she was impressed with him and wanted to marry him. A swayamvara was organized by Damayanti's father and Nala was also invited. Damayanti chose Nala out of the kings and princes and married. After a few years, they had two children...."
