तेन भाण्डेन संस्तीर्णं श्रीमद्राजनिवेशनम्।
अशोभत तदा भूयः शारदं गगनं यथा॥
tena bhāṇḍena saṁstīrṇaṁ śrīmad-rāja-niveśanam
aśobhata tadā bhūyaḥ śāradaṁ gaganaṁ yathā
tena = with those; bhāṇḍena = ornaments; saṁstīrṇam = strewn; śrīmat-rāja-niveśanam = the beautiful residence of the king; aśobhata tadā = shone; bhūyaḥ = again; śāradam = the autumn; gaganam = sky; yathā = like.
Strewn with those ornaments, the beautiful residence of the king again shone like the autumn sky.
“Autumn sky” means “a clear sky with stars.”
