यदिन्द्रो वर्षते वर्षं न तच्चित्रं भवेत्क्वचित्।आदित्यो वा सहस्रांशुः कुर्याद्वितिमिरं नभः।।4.39.2।।चन्द्रमा रश्मिभिः कुर्यात्पृथिवीं सौम्य निर्मलाम्।त्वद्विधो वाऽपि मित्राणां प्रतिकुर्यात्परन्तप ।।4.39.3।।
yad indro varṣate varṣaṁ na tac citraṁ bhavet kvacit |
ādityo vā sahasrāṁśuḥ kuryād vitimiraṁ nabhaḥ || 4.39.2 ||
candramā raśmibhiḥ kuryāt pṛthivīṁ saumya nirmalām |
tvad-vidho vāpi mitrāṇāṁ pratikuryāt parantapa || 4.39.3 ||
O scorcher of foes, gentle Sugrīva—there is nothing strange if Indra sends rain, if the thousand-rayed Sun clears the sky of darkness, and if the Moon makes the earth bright and cool with his beams; likewise it is only fitting that one like you should repay the service of friends.
'O scorcher of enemies, gentle Sugriva! it will not be strange if Indra showers rain, if the Sun in the sky dispels darkness with his thousand rays, and if the Moon cools down the earth with his light, and a person like you helps his friend.
Mitradharma—repaying and supporting friends who have helped you; gratitude and reciprocity are presented as natural and righteous, like rain from Indra or light from the Sun and Moon.
In the Kishkindhā alliance, Rāma underscores that Sugrīva’s assistance to his friends (especially Rāma and Lakṣmaṇa) is not extraordinary but the proper, expected course of dharma.
Kṛtajñatā (gratitude) and reliability in friendship—acting faithfully toward allies and returning help received.
