Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 45
Sanskrit:
सूर्येण हि विभज्यन्ते दिश: खं द्यौर्मही भिदा ।स्वर्गापवर्गौ नरका रसौकांसिच सर्वश: ॥ ४५ ॥
ITRANS:
sūryeṇa hi vibhajyantediśaḥ khaṁ dyaur mahī bhidāsvargāpavargau narakārasaukāṁsi ca sarvaśaḥ
Translation:
O King, the sun-god and the sun planet divide all the directions of the universe. It is only because of the presence of the sun that we can understand what the sky, the higher planets, this world and the lower planets are. It is also only because of the sun that we can understand which places are for material enjoyment, which are for liberation, which are hellish and subterranean.
