Śaṅkhaṇa’s son was the heroic and splendid Sudarśana; Sudarśana’s son was Agnivarṇa, and Agnivarṇa’s son Śīghraga. Śīghraga’s son was Maru; Maru’s son Praśuśruva; and Praśuśruva’s son was the radiant Ambarīṣa. Ambarīṣa’s son was Nahūṣa, whose prowess was true; Nahūṣa’s son was the supremely righteous Nābhāga. Nābhāga had two sons, Aja and Suvrata; and Aja’s son was the righteous king Daśaratha.
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.
It frames kingship as a dharmic inheritance: rulers are remembered not only by succession but by righteousness (paramadhārmika, dharmātmā) and truthful valor (satyavikrama).
The speaker traces the dynasty down to Daśaratha to establish the legitimacy and duty-bound continuity that culminates in Rāma.
Rajadharma—righteous rule rooted in truth (satya) and moral conduct (dharma), not merely bloodline.
