Śrī Rāmacandra-avatāra — Vow, Exile, Laṅkā-vijaya, and Rāma-rājya
Concise Bhāgavata Account
आरोप्यारुरुहे यानं भ्रातृभ्यां हनुमद्युत: । विभीषणाय भगवान् दत्त्वा रक्षोगणेशताम् । लङ्कामायुश्च कल्पान्तं ययौ चीर्णव्रत: पुरीम् ॥ ३२ ॥
āropyāruruhe yānaṁ bhrātṛbhyāṁ hanumad-yutaḥ vibhīṣaṇāya bhagavān dattvā rakṣo-gaṇeśatām laṅkām āyuś ca kalpāntaṁ yayau cīrṇa-vrataḥ purīm
Sau khi ban cho Vibhīṣaṇa quyền cai trị dân Rākṣasa ở Laṅkā cho đến hết một kiếp, Đức Bhagavān Śrī Rāmacandra đặt Sītādevī lên phi thuyền trang hoàng hoa, rồi chính Ngài cũng lên cùng các em và Hanumān; khi lời nguyện sống rừng đã mãn, Ngài trở về Ayodhyā.
This verse states that Lord Rāma personally granted Vibhīṣaṇa rulership over the Rākṣasas and the kingdom of Laṅkā, with dominion lasting until the end of the age (kalpānta).
Within the Rama narrative, Vibhīṣaṇa surrendered to Rāma and served dharma against Rāvaṇa; the Lord rewarded that devotion and righteousness by installing him as the rightful ruler of Laṅkā.
Honor commitments (vrata), protect dharma, and recognize sincere loyalty—Rāma’s conduct shows that integrity and faithful service should be acknowledged and empowered.
