The gods were worried because they thought that Dhruva was was praying so that he might obtain the power to defeat them. perhaps he wanted to become Indra, or the sun, or Kubera, Varuna or Soma. They went to Vishnu and asked him to stop Dhruva’s tapasya. Vishnu reassured the gods. He knew that these were not the things that Dhruva wanted.

Vishnu appeared before Dhruva and offered him a boon. The boy opened his eyes and saw Vishnu standing before him. He wanted the boon that he should always feel like praying to Vishnu. In fact, he did not really want boon at all. He had seen Visnu with his own eyes and there was nothing more that he desired. Vishnu was however so pleased that he persisted in granting Dhruva some boon. Dhruva then wanted the boon that he might attain a place that was on top of the entire world.

Vishnu told him that he would grant what Dhruva desired. He also told Dhruva that in an earlier life Dhruva had been a brahmana who was devoted to Vishnu. But the brahmana’s friend had been a wealthy and beautiful prince. Having got a boon from Vishnu, the brahmana had desired that in his next life he might be born a prince. That was the reason why he had been born as Dhruva, the son of King Uttanapada.
But since Dhruva no longer wanted kingdom or wealth, Vishnu would place him in the middle of the sky so that all the stars would revolve around him. His mother Suniti would also be placed in the sky near him.

Have you seen Dhruva in the sky? Of course you have. Near the seven sages who form the constellation of the Great bear. Dhruva is nothing but the Pole Star.
