सूर्यश्चास्तं गतस्तावत् तमसा चावृता दिश: । निम्नं कूलं जलमयं न प्राज्ञायत किञ्चन ॥ ३७ ॥

sūryaś cāstaṁ gatas tāvat tamasā cāvṛtā diśaḥ nimnaṁ kūlaṁ jala-mayaṁ na prājñāyata kiñcana

astam gataḥ
having set
tāvat
thereupon
tamasā
by darkness
ca
and

covered
diśaḥ
all the directions
nimnam

kūlam

Then, as the sun set, the forest was covered by darkness in every direction, and with all the flooding we could not distinguish high land from low.
