“O Brâhmana! I will suggest one way to you; kindly hear. The Devas ordained this long, long ago. You can give up your half life period, and with that you can make this girl alive soon.”
Ruru said:-- “O Deva messenger! I give half my life-period to this girl; there is no doubt in this. Let my beloved get back her life soon and get up.”
The king said:-- O Ministers! At this time Visvâvasu, knowing that his daughter Pramadvarâ is dead, descended from the Heavens in a celestial car and came to the place; then the Gandharva king and the Deva messenger both went to Yama, the Dharmarâj, and spoke thus:-- “O Dharmarâj! This Visvâvasu's daughter Pramadvarâ, the wife of Ruru, the Risis' son was bitten by a snake and has now come to your place. The Dvija Ruru is now desirous to quit his life; so, O Sun's son! Now let the girl again get her life through the influence of Ruru's brahmacharya (purity) as a consequence of his giving away half his life period for the girl.”
Dharma said:-- “O Deva messenger! if you want to make the girl alive again, let her get life as a consequence of half the life-period of Ruru being subtracted. Go immediately and give the girl to Ruru.”
The king said:-- “O Ministers! Yama having said thus to the Deva messenger, he went away immediately and made Pramadvarâ alive and handed her over to Ruru.
Thus, on an auspicious day, Ruru married her. Thus the Risis' daughter Pramadvarâ though fallen dead, got again her life by proper means. So, O Councillors! to save life, one should resort one's best duty according to the S’âstras, by the use of gems, mantras, and herbs and plants.”
Thus speaking to the ministers, the king Parîksit had a fine building of seven floors in height erected, placed the principal guards around it and stationed also the most powerful men well versed in the knowledge of mani (gems), mantrams, and plants for protection and immediately ascended to this building. To appease the wrath of the Muni S’ringî, the king sent the Muni named Gaurmukha to him and requested him repeatedly “Let the crime of the humble devotee be forgiven.” Then, for self preservation, the king brought from all sides the Brâhmanas, who are perfect in their knowledge and application of the mantras. The minister's son placed the elephants in proper places so that no body can ascend to the top of the building; what more can be said than the fact that even air could not find entrance there when once ordered “no admission” what to speak of others! The king Parîksit remained there and counted the number of days of the serpent Taksaka's coming there; he performed his bath, Sandhyâ Bandanams and fooding; even he consulted with his ministers and governed his kingdom from there. O Risis! At this time a Brâhman named Kas'yapa, versed in the mantras, heard of the curse of the king and thought that he would get abundant wealth if he could free the king from Taksaka's poison and proposed to himself that he would go to the place where the cursed king Parîksit was staying with the Brâhmanas. Pondering thus, the Brâhmana went out of his house, on the expectation of wealth from the king.
Thus ends the ninth chapter of the second Skandha on the account of Ruru in the Mahâpurânam S’rî Mad Devî Bhâgavatam of 18,000 verses.
