Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

By hearing these topics from the sage [Narada], the son of King Uttanapada [Dhruva] was enlightened regarding the Personality of Godhead, and he ascended to the abode of the Lord, placing his feet over the head of death.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

While quitting his body, Maharaja Dhruva, the son of King Uttanapada, was attended by personalities like Sunanda and others, who received him in the kingdom of God. He left this world at an early age, as a young boy, although he had attained the throne of his father and had several children of his own. Because he was due to quit this world, death was waiting for him. He did not care for death, however, and even with his present body he boarded a spiritual airplane and went directly to the planet of Visnu because of his association with the great sage Narada, who had spoken to him the narration of the pastimes of the Lord.
