Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued; My dear King, as stated before, the learned say that the sun travels over all sides of Manasottara Mountain in a circle whose length is 95,100,000 yojanas [760,800,000 miles]. On Manasottara Mountain, due east of Mount Sumeru, is a place known as Devadhani, possessed by King Indra. Similarly, in the south is a place known as Samyamani, possessed by Yamaraja, in the west is a place known as Nimlocani, possessed by Varuna, and in the north is a place named Vibhavari, possessed by the moon-god. Sunrise, midday, sunset and midnight occur in all those places according to specific times, thus engaging all living entities in their various occupational duties and also making them cease such duties.
