We now study Jambudweep is some detail. Jambudweep is round like sun with diameter of 100000 yojana and circumference of 300000 yojana. Mount Sumeru is located at the center of Jambudweep. Two circular arc shape mountain ranges are situated on east and west side of Sumeru as shown in fig 6.6. These mountain ranges provide two separate zones called north Kuru and south (deva) Kuru.
Jambudweep is divided into seven regions called Bharat, Haimvata, Harivarsha, Videh, Ramayaka, Hairanyavata and Airavata. Six Kaluchala Mountains respectively called Himavata, Mahahimavata, Nishadha, Neel, Raukmina, and Sikharin as shown in fig. 6.6 separate these regions. These mountains in order have colours like gold, silver, hot gold, blue gem, silver and gold. They have lakes (Rhud sasovar) called Padama, Mahapadama, Tigicha, Kesarin, Mahapundarika and Pundarika respectively on them. Rivers called Ganga and Sindhu, Rohita and Rohitasya, Harita and Harikanta, Sita and Sitoda, Nari and Narikanta, Swarnkula and Rupyakula, and Rakta and Raktoda flow in the seven regions. The Bharat region is 526 6 /19 yojana wide. The width of the next mountain is double this value. The width is doubled in the next region and so on till we reach the central Videha region. The widths are now halved for each mountain and region in order. Thus the width of Airavat region is same as width of Bharat region.
