The Mahabharata/Book 1: Adi Parva…
“ Vaisampayana continued, 'Hearing these words of the ascetics, Pandu, remembering the loss of his procreative powers owing to the curse of the deer, began to reflect deeply. And calling his wedded wife the excellent Kunti, unto him, he told her in private, 'Strive thou to raise offspring at this time of distress. The wise expounders of the eternal religion declare that a son, O Kunti, is the cause of virtuous fame in the three worlds. It is said that sacrifices, charitable gifts, ascetic penances, and vows observed most carefully, do not confer religious merit on a sonless man. ”
