Shloka 1.19.6
विश्वामित्रस्य यज्ञरक्षा-याचना (Visvamitra Requests Rama for Yajna-Protection)
अवधूते तथाभूते तस्मिन्नियमनिश्चये।।।।कृतश्रमो निरुत्साहस्तस्माद्देशादपाक्रमे।
svaputraṃ rājaśārdūla rāmaṃ satyaparākramam | kākapakṣadharaṃ śūraṃ jyeṣṭhaṃ me dātum arhasi ||
O tiger among kings, it is fitting that you entrust to me your own son—Rāma, the eldest—valiant, wearing youthful side-locks, and steadfast in true prowess.
The (solemn) vow for observance of religious rites being thus interrupted, I left that country as an exerted and discouraged man.
Rajadharma includes honoring a sage’s righteous request and supporting the protection of sacred rites, even when it requires personal sacrifice.
Viśvāmitra formally asks Daśaratha to send his eldest son Rāma with him for safeguarding the sacrifice.
Rāma’s dependable valor (satya-parākrama) is emphasized, and Daśaratha’s virtue of duty-bound generosity is implicitly invoked.
