एवमुक्तस्तु सुग्रीवो रामं वचनमब्रवीत्।।4.38.24।।प्रणष्टा श्रीश्च कीर्तिश्च कपिराज्यं च शाश्वतम्।त्वत्प्रसादान्महाबाहो पुनःप्राप्तमिदं मया।।4.38.25।।
tava deva prasādāc ca bhrātuś ca jayatāṃ vara | kṛtaṃ na pratikuryād yaḥ puruṣāṇāṃ sa dūṣakaḥ ||
ข้าแต่เทวะ ผู้ประเสริฐยิ่งในหมู่ผู้มีชัย ด้วยพระประสาทพรของพระองค์และของพระอนุชา กิจของข้าพเจ้าจึงสำเร็จ ผู้ใดไม่ตอบแทนคุณความดี ผู้นั้นเป็นที่ติเตียนในหมู่มนุษย์
On hearing this, Sugriva said to Rama,'O longarmed one the fortune, fame and soverignty of vanaras which was lost has been regained only by your grace.
Dharma is kṛtajñatā—repaying assistance and honoring obligations. Ingratitude is presented as a moral failing that degrades a person’s character.
Sugriva assures Rama that he understands the moral necessity of returning Rama’s help by actively aiding in the search for Sita.
Integrity in friendship—Sugriva frames repayment of help as an ethical duty, not merely political convenience.
