Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sukadeva Gosvami continued: My dear King, 1,300,000 yojanas [10,400,000 miles] above the planets of the seven sages is the place that learned scholars describe as the abode of Lord Visnu. There the son of Maharaja Uttanapada, the great devotee Maharaja Dhruva, still resides as the life source of all the living entities who live until the end of the creation. Agni, Indra, Prajapati, Kasyapa and Dharma all assemble there to offer him honor and respectful obeisances. They circumambulate him with their right sides toward him. I have already described the glorious activities of Maharaja Dhruva [in the Fourth Canto of Srimad-Bhagavatam].
