It is hyperbolic like a wide inverted bowl, slightly comparable to the upper part of the northern hemisphere and the mountain Meru lies at a place analogous to our North Pole.

That description does not, of course, correspond to the present knowledge of geography. Some of the details are akin to those of the Hindu concept. For instance, Hindu Puräns stipulate the existence of Jamboodweep and Meru of the sizes as per Jain concept.
