Shloka 5.1.100
समुद्रलङ्घनारम्भः — Commencement of the Ocean-Crossing
काकुत्स्थस्यानृशंस्यं च मैथिल्याश्च विवासनम्।।।।श्रमं च प्लवगेन्द्रस्य समीक्ष्योत्थातुमर्हसि।
kākutsthasyānṛśaṁsyaṁ ca maithilyāś ca vivāsanam |
śramaṁ ca plavagendrasya samīkṣyotthātum arhasi ||
If you consider the compassion of Rāma of the Kakutsthas, the unjust exile of Maithilī, and the strain borne by Hanumān, lord of monkeys, then you ought to rise and offer aid.
"You ought to rise up if you consider the nobility of the scion of the Kakusthas, the deportation of Mythili, and the exertion put forth by Hanuman, the lord of monkeys".
Dharma is to assist the righteous when their cause is just—compassion for Rāma, concern for Sītā’s suffering, and respect for Hanumān’s effort call for supportive action.
As Hanumān flies over the ocean, the ocean urges Maināka to rise and offer him rest and assistance.
Karunā (compassion) expressed as practical help—recognizing merit and responding with timely support.
