Srimad Bhagavatam Canto 05, Chapter 20, Text 45

SB 5.20.45

suryena hi vibhajyante
 disah kham dyaur mahi bhida
svargapavargau naraka
 rasaukamsi ca sarvasah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
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.
