Rāhu, Eclipses, Antarikṣa, and the Seven Subterranean Heavens
Bila-svarga
यत्र ह वाव न भयमहोरात्रादिभि: कालविभागैरुपलक्ष्यते ॥ ११ ॥
yatra ha vāva na bhayam aho-rātrādibhiḥ kāla-vibhāgair upalakṣyate.
Dahil walang sikat ng araw sa mga daigdig na nasa ilalim, hindi nahahati ang panahon sa araw at gabi; kaya’t wala roon ang takot na dulot ng paglipas ng panahon.
In Bhagavatam 5.24.11, Śukadeva explains that in that region the usual time divisions like day and night are not perceived, and thus fear is absent.
He links fear with the experience of time’s changes; where day-night style time markers are not recognized, the atmosphere is described as free from fear.
It suggests that fear increases when the mind is absorbed in changing time and circumstances; steadiness through spiritual focus reduces fear by rising above constant temporal anxiety.
