10.20.4

सान्द्रनीलाम्बुदैर्व्योम सविद्युत्स्तनयित्नुभि: । अस्पष्टज्योतिराच्छन्नं ब्रह्मेव सगुणं बभौ ॥ ४ ॥

sāndra

by the clouds
vyoma
the sky
sa-vidyut
along with lightning
stanayitnubhiḥ
and thunder
aspaṣṭa
diffuse
jyotiḥ
its illumination
ācchannam
covered
brahma
the spirit soul
iva
as if
sa-guṇam
with the material qualities of nature
babhau
was manifest

The sky was then covered by dense blue clouds accompanied by lightning and thunder. Thus the sky and its natural illumination were covered in the same way that the spirit soul is covered by the three modes of material nature.
