His Minister Sumantra advised him to invite Rshyashringa to perform a yajna for begetting a child. Lomapada and Santa requested Rshyashringa to comply with the desire of Dasaratha. Rshyashringa could not refuse the King's request as the king was his father-in-law. He arrived at Ayodhya and performed a yajna called Putrakamesti(sacrifice for getting children) under the guidance of Vasistha. The air vibrated with the recitation of mantras (spells and incantations) and the Veda Suktas. The hermit uttered the divine spell of Putrakamesti and offered oblations in the sacrificial fire. From the sacrificial fire there arose a dark monstrous / wonderful and luminous figure, with a pot of pudding of ambrosia before Rshyashringa and then disappeared in the sacrificial fire. Dasaratha received it from him and in accordance with the instruction of the hermit, gave one half of it to Kausalya and the other half to Kaikeyi. Both of them gave half of their shares to Sumitra. Thus the three wives ate the divine pudding and by and by all of them became pregnant. Sumitra got two shares while the other two wives of Dasaratha got only one share each. As a result Kausalya and Kaikeyi gave birth to a son each, while Sumitra had two sons. Kausalya's son was named Rama, Kaikeyi's son was Bharata and Sumitra's sons were Laksmana and Satrughna.<ref>Valmiki Ramayana, Bala Kanda, Chapters 14-16 | His Minister Sumantra advised him to invite Rshyashringa to perform a yajna for begetting a child.
