Rāhu, Eclipses, Antarikṣa, and the Seven Subterranean Heavens
Bila-svarga
ततोऽधस्ताच्छतयोजनान्तर इयं पृथिवी यावद्धंसभासश्येनसुपर्णादय: पतत्त्रिप्रवरा उत्पतन्तीति ॥ ६ ॥
tato ’dhastāc chata-yojanāntara iyaṁ pṛthivī yāvad dhaṁsa-bhāsa-śyena-suparṇādayaḥ patattri-pravarā utpatantīti.
ततोऽधस्तात् तेषां विहारस्थानानां शतयोजनान्तर इयं पृथिवी; यावद्धंसभासश्येनसुपर्णादयः पतत्त्रिप्रवरा उत्पतन्ति तावदस्योर्ध्वसीमा ॥
This verse states that the earthly plane (pṛthivī) is situated one hundred yojanas below the previously described region.
Śukadeva uses a familiar natural benchmark—how high great birds can fly—to indicate the extent of the earthly region being described.
It cultivates humility and God-centered perspective by reminding a devotee that the cosmos is vast and systematically governed, encouraging steadiness in bhakti rather than material pride.
