After a long reign, Dhruva wishes to seek God's feet and spend the rest of his time in devotional service to God. He renounces his kingdom and goes to the Himalayas to do penance. At the end of his life-term, Vishnu's attendants come to fetch him to his special abode.
The lord of Death hastened to this scene to pay respects to this pure soul, Dhruva. Death bowed his head so that Dhruva could mount the divine chariot that remained suspended above the ground. Dhruva then remembered his mother and did not want to go without her. The divine attendants assured Dhruva that his mother was already on her way to the Supreme abode.
