2.2.23

bhadrāśvaṃ pūrvato meroḥ ketumālaṃ ca paścime
varṣe dve tu muniśreṣṭha tayor madhyam ilāvṛtam //

The country of Bhadráśwa lies on the east of Meru, and Ketumála on the west; and between these two is the region of Ilávrita. On the east of the same is the forest Chaitraratha; the Gandhamádana wood is on the south; the forest of Vaibhrája is on the west; and the grove of Indra, or Nandana, is on the north. There are also four great lakes, the waters of which are partaken of by the gods, called Aruńoda, Mahábhadra, Śítoda, and Mańasa.
