maitreya uvaca

adhirajasanam pituh
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The great sage Maitreya replied: My dear Vidura, when Maharaja Dhruva departed for the forest, his son, Utkala, did not desire to accept the opulent throne of his father, which was meant for the ruler of all the lands of this planet.
