King Dasharatha, seeking progeny, organizes the Aswamedha ritual with Sage Rishyasringa presiding on the northern bank of the Sarayu River. Scholars warn that strict adherence to scriptural rules is essential to prevent Brahma demons from ruining the sacrifice and ensuring the birth of four powerful sons. Vishnu agrees to incarnate as Dasharatha’s sons to defeat Ravana, who holds a boon making him invulnerable to all beings except humans. The gods simultaneously create vanara warriors to support this mission.

Vishvamitra urges Dasharatha to send Rama to destroy demons disrupting his sacrifice. After Rama kills the demoness Tataka and defeats Mareecha and Subaahu during the ritual, Vishvamitra recounts divine origins, including the descent of Ganga to purify the ashes of Sagara’s sixty thousand sons. He also narrates the curse of Ahalya and the conflict between his ascetic power and Vashishta’s lineage. Later, King Janaka of Mithila offers his daughter Sita to Rama, stipulating she will marry only the prince capable of stringing her father’s sacred bow. Rama breaks the bow, securing Sita’s hand. Janaka traces his ancestry to confirm his right to rule and marry his daughters. The remaining princes are matched with Janaka’s kin, leading to quadruple weddings. Dasharatha performs cow donations before the ceremonies. Rama and Lakshmana serve Dasharatha, managing civic welfare and establishing Rama as a truthful protector.
