In time, he became one of the world's greatest heroes. After the birth of the child, Kunti once again became a virgin as a result of the boon granted by the Sun. She wondered what she should do with the child. To hide her fault she placed the child in a sealed box and set it afloat in a river. A childless charioteer happened to see the floating case, and taking it, was surprised and delighted to see within it a gorgeously beautiful child. He handed it over to his wife who lavished a mother's love on it. Thus Karna, the son of the Sun god, came to be brought up as a charioteer's child. When the time came for giving Kunti in marriage, Kuntibhoja invited all the neighboring princes and held a swayamvara for her to choose her husband. Many eager suitors flocked to the swayamvara as the princess was widely famed for her great beauty and virtue. Kunti placed the garland on the neck of King Pandu, the bright representative of the Bharata race, whose personality eclipsed the lustre of all the other princes assembled there. The marriage was duly solemnised and she accompanied her husband to his capital Hastinapur. On the advice of Bhishma and in accordance with the prevailing custom, Pandu took a second wife Madri, the sister of the king of Madra. In the old days the kings took two or three wives for making sure of progeny and not for mere sensual desire.
