The example of Dhruva Maharaja is that he engaged himself in devotional service to the Lord according to the order of his spiritual master, Narada Muni. As a result of his rendering such devotional service with great determination and austerity, the Personality of Godhead personally manifested Himself before him. Dhruva was only a child. He wanted to offer nice prayers to the Lord, but because he lacked sufficient knowledge, he hesitated; but by the mercy of the Lord, as soon as the Lords conchshell touched his forehead, he became completely aware of the Vedic conclusion. That conclusion is based on proper understanding of the difference between jiva and Paramatma, the individual soul and the Supersoul. The individual soul is forever a servant of the Supersoul, and therefore his relationship with the Supersoul is to offer service. That is called bhakti-yoga, or bhakti-bhava. Dhruva Maharaja offered his prayers to the Lord not in the way of the impersonalist philosophers, but as a devotee. Therefore, it is clearly said here, bhakti-bhava. The only prayers worth offering are those offered to the Supreme Personality of Godhead, whose reputation is spread far and wide. Dhruva Maharaja wanted to have the kingdom of his father, but his father refused even to allow him to get on his lap. In order to fulfill his desire, the Lord had already created a planet known as the polestar, Dhruvaloka, which was never to be annihilated even at the time of the dissolution of the universe. Dhruva Maharaja attained this perfection not by acting hastily, but by patiently executing the order of his spiritual master, and therefore he became so successful that he saw the Lord face to face. Now he was further enabled, by the causeless mercy of the Lord, to offer fitting prayers to the Lord. To glorify or offer prayers unto the Supreme, one needs the Lords mercy. One cannot write to glorify the Lord unless one is endowed with His causeless mercy.
