After pondering for a while in spiritual contemplation, Rshyasringa master of the vedas said, "I shall perform Putreyshti for you to beget sons with the aid of mantras as in Atharvasirasi". When the ritual commenced the gods, gandharvas,all the spiritually accomplished sages and Brahma the creator assembled to receive their share of the ritual offerings as was the custom. At this time the assembly of celestials told Brahma of their troubles. "Oh Lord! A rakshasa by name Ravana armed with the boon granted by you is tormenting us. His diabolic powers leave us powerless. Unable to chastise him and honoring the boon granted by you, we bear the havoc that he creates. With arrogance born of that power the evil demon makes the three worlds tremble with fear. Rendered invincible he spares neither asuras, Brahmins or gandharvas. We dread him. Even the Sun shines subdued, the winds dare not to blow and the restless oceans still at his appearance".
Brahmasaid that it was true Ravana was armed with a boon worded in such a way that it rendered him virtually deathless. In asking for the boon he had sought immunity from every celestial and from every creature born on earth but of man there was no mention. In his insolence he felt humiliated to seek immunity from their paltry strength which in his disdain he even refused to recognize. "So Ravana will die and die in the hands of man. His death has already been ordained".Even as the celestials were rejoicing Visnu attired in yellow bearing conch, mace and discus appeared in all his glory. The divine gathering prostrated to that god of gods entreating him to be born as human and rid the world of Ravana. Allaying their fears and bowing to their wishes Visnu promised not only to slay Ravana but also his sons and his kin. He pondered for a moment as to where he should be born? . He then decided to divide himself into four parts to be born as Dasaratha's four sons. "Do that" urged the celestials, "and return soon to Vaikunta, that permanent abode of yours devide of all passion hatred and sin beyond reach of even the celestials.
