Kulasekhara was born in the famous Chera dynasty at Vanchi in Kali Era 28. When Kulasekhara came of age, his father Dridhavrata abdicated the kingdom and retired from public life, and the new king ascended the throne. The king was a great devotee of god Vishnu. His piety was so great that on one occasion when the story was being narrated as to how demon king Ravana abducted princess Sita, he at once issued orders to marshall out his army for the invasion of Lanka. A minister who felt jealous of the favour showered by the king on Vaishnavites, trumped up on the devotees a false charge. The king vindicated their innocence by inserting his hand in a pot containing snakes and drawing it out unscathed.
