7. Thus they say that a distance of 9 crores and 51 lacs of Yojanas is traversed by the Sun in going round the Manasottara mountain. On that mountain, to the east of Meru there is the city of Indra known as Devadhani (abode of the gods); on the south is the city of Samyamani ruled over by Yama; on the west is the city of Varuna, known as Nimlochini; and on the North is the city of Soma called Vibhavari; on the four sides of Meru by the particular points of time, the conditions necessary for the activity and inactivity of beings are instituted by the Sun's passage through those cities and they are known as Sunrise, Midday, and Sunset and Midnight.
