etaval loka-vinyaso mana-laksana-samsthabhir vicintitah kavibhih sa tu pancasat-koti-ganitasya bhu-golasya turiya-bhago ’yam lokalokacalah.
etavan—this much; loka-vinyasah—the placing of the different planets; mana—with measurements; laksana—symptoms; samsthabhih—as well as with their different situations; vicintitah—established by scientific calculations; kavibhih—by learned scholars; sah—that; tu—but; pancasat-koti—500,000,000 yojanas; ganitasya—which is measured at; bhu-golasya—of the planetary system known as Bhugolaka; turiya-bhagah—one fourth; ayam—this; lokaloka-acalah—the mountain known as Lokaloka.
Learned scholars who are free from mistakes, illusions and propensities to cheat have thus described the planetary systems and their particular symptoms, measurements and locations. With great deliberation, they have established the truth that the distance between Sumeru and the mountain known as Lokaloka is one fourth of the diameter of the universe—or, in other words, 125,000,000 yojanas [1 billion miles].
Srila Visvanatha Cakravarti Thakura has given accurate astronomical information about the location of Lokaloka Mountain, the movements of the sun globe and the distance between the sun and the circumference of the universe. However, the technical terms used in the astronomical calculations given by the Jyotir Veda are difficult to translate into English. Therefore to satisfy the reader, we may include the exact Sanskrit statement given by Srila Visvanatha Cakravarti Thakura, which records exact calculations regarding universal affairs.
