Vyâsa said:-- O King! The King Yauvanâs'va had one hundred queens; yet he had no issues. The King always thought much about his son. Once the King, sorry and desirous of a son, went to the holy retreats of the Risis. On arriving there, he began frequently to respire heavily before the ascetics. The Risis became filled with pity on seeing his sorrowful condition. O King! The Brâhmins that said to him:-- O King! Why are you thus sorrowful and distressed? What is your sorrow that is troubling your heart? Speak truly. We will surely redress your grievance.
