King Khatvanga was unconquerable in any fight. Requested by the demigods to join them in fighting the demons, he won victory, and the demigods, being very pleased, wanted to give him a benediction. The King inquired from them about the duration of his life and was informed that he had only one moment more. Thus he immediately left his palace and went to his own residence, where he engaged his mind fully on the lotus feet of the Lord.
