PURPORT

Suniti cited the example of Lord Brahma, who was Dhruva Maharaja's great-grandfather. Although Lord Brahma is also a living being, by his penance and austerity he acquired the exalted position of creator of this universe by the mercy of the Supreme Lord. To become successful in any attempt, one not only has to undergo severe penances and austerities, but also must be dependent on the mercy of the Supreme Personality of Godhead. This indication had been given to Dhruva Maharaja by his stepmother and was now confirmed by his own mother, Suniti.
