4.4.p13

The son of Khatwanga was Dirghābahu, whose son was Raghu, whose son was Aja, whose son was Dasaratha. The glorious god, from whose navel the lotus springs, was born for the protection of the world, as the four sons of Dasaratha—namely Rāma, Lakshmana, Bharata and Satrughna. While a boy Rāma was taken by Viswamitra to protect his sacrifice and slew Tadakā. In the sacrifice, Māricha was slain and thrown away. Suvahu and others were also slain by him. He removed the iniquity of Ahalyā by merely looking upon her. Arriving at the palace of Janaka he easily broke the bow of Maheswara, and received Sitā, self-born daughter of the king Janaka as the meed for his prowess. He humbled the pride of Parusharama—the Ketu of the Haihaya race and the slayer of all Kshatriyas. At the behest of his sire and not being sorry for the loss of kingdom he went to woods accompanied by his brother Lakshmana and his wife, where he destroyed in battle Viradha, Kara, Dusana and other Rākshasas, the headless demon Kavandha and Vali the king of monkeys. Having constructed a bridge across the deep and slain all the Rākshasas, he brought back his spouse Sitā who had been carried away by the Ten-necked Rāvana. Having purified her by the fiery ordeal, and accordingly her virtue chanted by the celestials, he returned with her to Ayodhyā.
