Srimad Bhagavatam 5.24.11

5.24.11

यत्र ह वाव न भयमहोरात्रादिभि: कालविभागैरुपलक्ष्यते ॥ ११ ॥

yatra ha vava na bhayam aho-ratradibhih kala-vibhagair upalaksyate.

yatra
where
ha vava
certainly
na
not
bhayam
fearfulness
ahah-ratra-adibhih
because of days and nights
kala-vibhagaih
the divisions of time
upalaksyate
is experienced.

Since there is no sunshine in those subterranean planes, time is not divided into days and nights, and consequently fear produced by time does not exist.
