His Minister Sumantra advised him to invite Rshyashrnga to perform a yajna for begetting a child. Lomapada and Shanta requested Rshyashrnga to comply with the desire of Dasharatha. Rshyashrnga 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(yajna 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 yajnika agni. From the yajnika agni there arose a dark monstrous / wonderful and luminous figure, with a pot of pudding of ambrosia before Rshyashrnga and then disappeared in the yajnika agni. Dasharatha 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 Dasharatha 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 name=":1" /><ref>Valmiki Ramayana, Bala Kanda, Chapters 14-16 | His Minister Sumantra advised him to invite Rshyashrnga to perform a yajna for begetting a child.
