Srimad Bhagavatam Canto 04, Chapter 09, Text 37

SB 4.9.37

 akarnyatma-jam ayantam
 samparetya yathagatam
raja na sraddadhe bhadram
 abhadrasya kuto mama
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When King Uttanapada heard that his son Dhruva was coming back home, as if coming back to life after death, he could not put his faith in this message, for he was doubtful of how it could happen. He considered himself the most wretched, and therefore he thought that it was not possible for him to attain such good fortune.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Dhruva Maharaja, a five-year-old boy, went to the forest for penance and austerity, and the King could not at all believe that a small boy of such a tender age could live in the forest. He was certain that Dhruva was dead. He therefore could not fix his faith in the message that Dhruva Maharaja was coming back home again. For him this message said that a dead man was coming back home, and so he could not believe it. After Dhruva Maharaja’s departure from home, King Uttanapada thought that he was the cause of Dhruva’s leaving, and thus he considered himself the most wretched. Therefore, even though it was possible that his lost son was coming back from the kingdom of death, he thought that since he was most sinful it was not possible for him to be so fortunate as to get back his lost son.
