तथैवेलावृतमपरेण पूर्वेण च माल्यवद्गन्धमादनावानीलनिषधायतौ द्विसहस्रं पप्रथतु: केतुमालभद्राश्वयो: सीमानं विदधाते ॥ १० ॥
tathaivelāvṛtam apareṇa pūrveṇa ca mālyavad-gandhamādanāv ānīla-niṣadhāyatau dvi-sahasraṁ paprathatuḥ ketumāla-bhadrāśvayoḥ sīmānaṁ vidadhāte.
In the same way, west and east of Ilāvṛta-varṣa are two great mountains named Mālyavān and Gandhamādana respectively. These two mountains, which are 2,000 yojanas [16,000 miles] high, extend as far as Nīla Mountain in the north and Niṣadha in the south. They indicate the borders of Ilāvṛta-varṣa and also the varṣas known as Ketumāla and Bhadrāśva.
