Valmiki Ramayana · Ayodhya Kanda · Sarga 2
अनुरूपस्स वै नाथो लक्ष्मीवान् लक्ष्मणाग्रजः। त्रैलोक्यमपि नाथेन येन स्यान्नाथवत्तरम्
anurūpassa vai nātho lakṣmīvān lakṣmaṇāgrajaḥ| trailokyamapi nāthena yena syānnāthavattaram
With him (Rama) as ruler, all the three worlds will also have a better protector.That elder brother of Lakshmana with signs of greatness is certainly the most befitting to rule this kingdom.
— M.N. Dutt (1891)
Commentary
With Rama as ruler, even the three worlds will have a better protector. The statement expands the scope of the coronation beyond Ayodhya — Rama's rule will benefit heaven and earth alike. Lakshmana's mention as 'that elder brother of Lakshmana' reframes Rama through the devotion of his brother.
