Aparakāśi (Aparakasi) is the name of one ancient locality in Bhāratavarṣa (Bharatavarsha; India). It is probably located towards the west of the major portion of Kāśī (Kasi).
Here we have seen the name of ‘Kāsī’ appearing as Kāśi. In Mahābhārata (Mahabharata), the plural number of this name is used as ‘Kāśayaḥ’ (Kasayah), ‘Aparakāśayaḥ’ (Aparakasayah). If it was spelt with dīrgha ī (long i), the plural form should have been Kāśyaḥ (Kasyah).
