When the sages found that the water had been drunk, they made the query as to who had drunk the same. The king Yuvanaswa said that he had drunk it unwittingly. He conceived and in the course of time gave birth to a child from his right side. The boy, who was named Mandhatri (or Mandhata) grew up and became a mighty monarch. He married Hindumati and by her had three sons and fifty daughters. All the fifty daughters were married to the sage Saibhari.
