pūrvaje nāparaḥ putro jyeṣṭho rājyebhiṣicyate ||
Among all the Ikṣvākus, the eldest becomes king; while the eldest lives, a younger son is not consecrated to the kingdom.
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.
Maryādā (constitutional tradition): legitimate succession protects social order; dharma is upheld by honoring established norms of inheritance.
The speaker justifies Rāma’s claim by citing the ancestral rule of succession in the Ikṣvāku dynasty.
Respect for tradition and lawful order as a foundation for stable governance.
