स तं कैलासशृङ्गाभं प्रासादं नरपुङ्गवः।।2.3.31।। आरुरोह नृपं द्रष्टुं सह सूतेन राघवः।
sa taṃ kailāsaśṛṅgābhaṃ prāsādaṃ narapuṅgavaḥ āruroha nṛpaṃ draṣṭuṃ saha sūtena rāghavaḥ|
Best among men, Rama accompanied by charioteer Sumantra ascended that palace that was lofty as the peak of Kailasa mountain in order to see the king.
— M.N. Dutt (1891)
Commentary
Rama ascends the palace, which is as lofty as the peak of Kailasa. The comparison to Shiva's mountain connects Rama's kingship to the highest spiritual authority. He climbs toward his destiny as one climbs toward the gods.
