In this verse the word mānava is very significant. Generally this word is used to mean "human being." Dhruva Mahārāja is also described here as mānava. Not only is Dhruva Mahārāja a descendant of Manu, but all human society descends from Manu. According to Vedic civilization, Manu is the lawgiver. Even today Hindus in India follow the laws given by Manu. Everyone, therefore, in human society is a mānava, or descendant from Manu, but Dhruva Mahārāja is a distinguished mānava because he is a great devotee.
The denizens of the planet Siddhaloka, where the residents can fly in the sky without airplanes, were anxious over Dhruva Mahārāja's welfare in the battlefield. Śrīla Rūpa Gosvāmī says, therefore, that not only is a devotee well protected by the Supreme Lord, but all the demigods, and even ordinary men, are anxious for his security and safety. The comparison given here that Dhruva Mahārāja appeared to merge in the ocean of the Yakṣas is also significant. When the sun sets on the horizon, it appears that the sun drowns in the ocean, but factually the sun has no difficulty. Similarly, although Dhruva appeared to drown in the ocean of the Yakṣas, he had no difficulty. As the sun rises again in due course at the end of night, so Dhruva Mahārāja, although he might have been in difficulty (because, after all, it was a fight, and in any fighting activities there are reverses), that did not mean that he was defeated.
