We are now going to discuss the movement of the sun.
**Question:** How does the sun move?
**Answer:**
The Jambudvipa island, along with all the other islands and oceans, is a circular landmass with a diameter of 100,000 yojanas. It is further specified that the diameter is 300,000 yojanas, 227 yojanas, 300 kosas, 28 dhanus, 13 angulas, and half an angula.
1. When the sun moves through the entire outer circle, it takes 18 muhurtas for a day, which is equivalent to 12 muhurtas of night.
2. When the sun starts its journey in the first year, it moves through the first inner circle. The sun moves through this circle with a speed of 2 yojanas and 49/64 of a yojana, vibrating with each movement. This takes 18 muhurtas for a day, which is equivalent to 12 muhurtas of night, minus 1/64 of a muhurta.
3. When the sun starts its journey in the second year, it moves through the second inner circle. The sun moves through this circle with a speed of 5 yojanas and 35/64 of a yojana, vibrating with each movement. This takes 18 muhurtas for a day, which is equivalent to 12 muhurtas of night, minus 1/16 of a muhurta.
4. In this way, the sun moves through all the inner circles, each time increasing its speed by 2 yojanas and 49/64 of a yojana, vibrating with each movement. Finally, it reaches the outermost circle.
5. When the sun moves through the outermost circle, it moves with a speed of 155 yojanas, vibrating with each movement.
