You are his eldest heir, widely renowned as Rāma. Therefore, O king, accept your own kingdom and look after the people.
The son of Shankhana was the glorious Sudarshana, father of Agnivarna. Shighraga was the son of Agnivarna whose son was Maru. Maru's son was Prashushruva and to Prashushruva was born splendid Ambarisha. Nahusha of indisputable prowess was the son of Ambarisha whose son was the supremely righteous Nabhaga. Nabhaga had two sons, Aja and Suvrata and Aja's son was the righteous king Dasaratha.
Rajadharma: the rightful heir should accept responsibility to protect and govern the people, treating kingship as duty rather than privilege.
After establishing Daśaratha’s lineage, the speaker urges Rāma to take up the kingdom as the eldest heir.
Responsibility and guardianship—leadership expressed as care for the people.
