In terms of our lives, the distance of five hundred yojana signifies our life

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. (SB 5.23.9 p.)


The moon is situated 100,000 yojanas above the rays of the sunshine.

Rahu is situated 10,000 yojanas below the sun. Below Rahu by another 10,000 yojanas are the planets of the Siddhas, Caranas and Vidyadharas, and below these are planets such as Yaksaloka and Raksaloka. Below these planets is the earth, and 70,000 yojanas below the earth are the lower planetary systems Bila-svarga: Atala, Vitala, Sutala, Talatala, Mahatala, Rasatala and Patala. Demons and Raksasas live in these lower planetary systems with their wives and children, always engaged in sense gratification and not fearing their next births. The sunshine does not reach these planets, but they are illuminated by jewels fixed upon the hoods of snakes. Because of these shining gems there is practically no darkness.

The extent of the cosmic phenomenon is calculated to be diametrically (both ways) four billion miles. Then the coverings of the universe begin.
