TRANSLATION

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 Lokāloka is one fourth of the diameter of the universe—or, in other words, 125,000,000 yojanas [1 billion miles].

PURPORT

Śrīla Viśvanātha Cakravartī Ṭhākura has given accurate astronomical information about the location of Lokāloka 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 Śrīla Viśvanātha Cakravartī Ṭhākura, which records exact calculations regarding universal affairs.
