Srimad Bhagavatam 9.18.49

9.18.49

यस्मिन्निदं विरचितं व्योम्नीव जलदावलि: । नानेव भाति नाभाति स्वप्नमायामनोरथ: ॥ ४९ ॥

yasminn idam viracitam vyomniva jaladavalih naneva bhati nabhati svapna-maya-manorathah

yasmin
in whom
idam
this entire cosmic manifestation
viracitam
created
vyomni
in the sky
iva
just like
jalada-avalih
clouds
nana iva
as if in different varieties
bhati
is manifested
na abhati
is unmanifested
svapna-maya
illusion, like a dream
manah-rathah
created to be traversed by the chariot of the mind.

The Supreme Lord, Vasudeva, who created the cosmic manifestation, exhibits Himself as all-pervading, like the sky that holds clouds. And when the creation is annihilated, everything enters into the Supreme Lord, Visnu, and varieties are no longer manifested.
