Chapter 45 of the Kūrma Purāṇa continues the grand cosmographical exposition by offering a detailed description of Bhūloka — the terrestrial realm — within the structure of the cosmic egg (brahmāṇḍa). Sūta, the narrator, introduces the seven sacred continents (dvīpas), arranged concentrically and expanding outward, each surrounded by oceans made of progressively more wondrous substances. These continents are: Jambū, Plakṣa, Śālmalī, Kuśa, Krauñca, Śāka, and Puṣkara. Each is larger than the last, and each is girdled by an ocean of increasing vastness and variety: salt water, sugarcane juice, wine, ghee, curds, milk, and sweet water, respectively. Together, they form the terrestrial domain, measured as fifty crores (500 million) yojanas in extent.
At the center of this cosmic geography lies Jambūdvīpa, the most sanctified of all the continents and the origin of human civilization. At the very heart of Jambūdvīpa stands the resplendent Mount Meru, radiant with golden brilliance. It rises 84,000 yojanas into the sky, with 16,000 submerged below the surface. At its summit, Meru spans 32,000 yojanas wide and narrows to 16,000 yojanas at the base, like the pericarp of a massive lotus. Surrounding Mount Meru are six great mountain ranges — three to the south (Himavān, Hemakūṭa, Niṣadha) and three to the north (Nīla, Śveta, Śṛṅgī). These form boundaries for the seven regional divisions (varṣas) of Jambūdvīpa: to the south are Bhāratavarṣa, Kimpuruṣa, and Harivarṣa; to the north are Ramyaka, Hiraṇmaya, and Uttarakuru; and at the very center lies Ilāvṛta-varṣa, which envelops the upper part of Mount Meru.
Ilāvṛta-varṣa is 9,000 yojanas wide and serves as a celestial center, flanked by four great “viṣkambha” mountains — Mandara, Gandhamādana, Vipula, and Suparśva — situated in the cardinal directions around Meru. Each of these sacred mountains hosts a divine tree: the Kadamba on Mandara, the Jambū (rose-apple) on Gandhamādana, the Pippala (sacred fig) on Vipula, and the Banyan (Vaṭa) on Suparśva. The continent of Jambūdvīpa itself is named after the legendary Jambū tree, whose enormous fruits fall on the mountainsides and yield rivers of juice. The most famous of these is the Jambū-nadī, whose sweet nectar sustains the region’s inhabitants, making them free from aging, disease, sweat, odor, and mental afflictions. When the river’s juice dries upon the earth, it crystallizes into Jāmbūnada gold, prized by the Siddhas for ornamentation.
Surrounding Ilāvṛta-varṣa are other divine regions: Bhadrāśva to the east and Ketumāla to the west, each filled with forests and lakes of divine origin. Among these are the sacred forests: Caitraratha, Gandhamādana, Vaibhrāja, and Savitṛ, associated with gods, sages, and solar deities. Four holy lakes — Aruṇoda, Mahābhadra, Asitoda, and Mānasa — are described as sanctuaries where celestial beings find joy. The region is also adorned with an immense number of mountains, including Sītānta, Kumudvān, Kururī, and Mālyavān, as well as Kailāsa, Himavān, and Mandara, all described as divine habitations of Siddhas, Yakṣas, Gandharvas, and righteous ṛṣis.
The text then offers exhaustive lists of sacred mountains in each direction of the central lakes — east, south, west, and north — such as Kapila, Sarvagandha, Citraśṛṅga, Mahālaya, Puṇḍarīka, Mahāmegha, Śaṅkhakūṭa, Vārāha, Mayūra, and Kanaka, among many others. These are revered as the thrones of sages, perfected beings, and divine spirits, resounding with sacred austerities. Between these towering ranges lie serene valleys, lakes, and hidden forests, where ascetic sages dwell in profound tranquility, absorbed in Brahman, liberated from sorrow and unbound by worldly attachment.
