Shloka 4.8.25
मैत्रीप्रतिज्ञा-वैरकारणप्रश्नः (Friendship Vow and Inquiry into the Cause of Enmity)
राघवस्य वचश्श्रुत्वा सुग्रीवो वाहिनीपतिः।प्रहर्षमतुलं लेभे साधु साध्विति चाब्रवीत्।।
rāma śokābhibhūto 'haṃ śokārtānāṃ bhavān gatiḥ | vayasya iti kṛtvā hi tvayy ahaṃ paridevaye ||
O Rāma, I am overcome by sorrow; you are the refuge of the grief-stricken. Taking you as my friend, I pour out my lament to you.
On hearing Rama's words, Sugriva, chief of the army of monkeys experienced immeasurable happiness and exclaimed, 'you're great, you're great.'
Dharma includes offering refuge and attentive support to the afflicted; friendship becomes a moral shelter for truthful lament.
Sugrīva, reassured, opens his heart to Rāma and frames him as his protector and confidant.
Sugrīva’s sincerity and trust, and implicitly Rāma’s role as compassionate refuge.
