The Dhruva-stuti as mentioned in the Vishnu Purana. Having spent a long time in the Lord's remembrance he even forgot the objective of his tapasya, and only asked for a life in memory of the Lord. Pleased by his tapasya and by his stuti, Vishnu granted his wish and further decreed that the lad would attain Dhruvapada - the state where he would become a celestial body which would not even be touched by the Maha Pralaya, or the final cataclysm.
