Summarizing the entire description of the planetary systems of the universe, Srila Visvanatha Cakravarti Thakura says that one who is able to meditate upon this arrangement as the virat-rupa, or visva-rupa, the external body of the Supreme Personality of Godhead, and worship Him three times a day by meditation will always be free from all sinful reactions. Visvanatha Cakravarti Thakura estimates that Dhruvaloka, the polestar, is 3,800,000 yojanas above the sun. Above Dhruvaloka by 10,000,000 yojanas is Maharloka, above Maharloka by 20,000,000 yojanas is Janaloka, above Janaloka by 80,000,000 yojanas is Tapoloka, and above Tapoloka by 120,000,000 yojanas is Satyaloka. Thus the distance from the sun to Satyaloka is 233,800,000 yojanas, or 1,870,400,000 miles. The Vaikuntha planets begin 26,200,000 yojanas (209,600,000 miles) above Satyaloka. Thus the Visnu Purana describes that the covering of the universe is 260,000,000 yojanas (2,080,000,000 miles) away from the sun. The distance from the sun to the earth is lower planetary systems called Atala, Vitala, Sutala, Talatala, Mahatala, Rasatala and Patala. Below these lower planets by 30,000 yojanas, Sesa Naga is lying on the Garbhodaka Ocean. That ocean is 249,800,000 yojanas deep. Thus the total diameter of the universe is approximately 500,000,000 yojanas, or 4,000,000,000 miles.
