[Samvayanga Sutra Avasa-Pavvayana.
The Go-stupa Avasa-parvata is located at a distance of one thousand yojanas from the westernmost part of the Mandara mountain, which is in the middle of the Jambudvipa. Similarly, the distance between all four Avasa-parvatas should be known.
Discussion - The boundary of Jambudvipa extends fifty thousand yojanas in all four directions from the middle of Mount Meru. From there, the four Avasa-parvatas, including Go-stupa, are located at a distance of forty-eight thousand yojanas within the Lavana-samudra in all four directions. Therefore, the distance between each Avasa-parvata and the middle of Mount Meru is proven to be one thousand yojanas.

The thirteenth Gan and the thirteenth Ganadhara belonged to Chandra-prabha Arhat. There were thirteen hundred (9300) fourteen- पूर्वी in the Sangha of Shanti Arhat.
The sun, while moving from Dakshinayana to Uttarayana or returning from Uttarayana to Dakshinayana, makes the equal day and night unequal on the thirteenth mandala.
Discussion - There are 184 mandalas of the sun's movement. When the sun moves on the innermost mandala above Jambudvipa, the day is eighteen muhurtas and the night is twelve muhurtas. Similarly, when the sun moves on the outermost mandala above the Lavana-samudra, the day is twelve muhurtas and the night is eighteen muhurtas. Similarly, when the sun moves on the thirteenth mandala while going to Uttarayana or returning to Dakshinayana, both day and night are equal, i.e., fifteen muhurtas each. If it moves further north, the day starts increasing and the night starts decreasing. And if it moves south, the night starts increasing and the day starts decreasing. Keeping this arrangement in mind, it is said that the sun on the thirteenth mandala, while moving forward or returning, makes the equal day and night unequal.
