Ekāsana (Ekasana) is an ancient non-Aryan tribe. According to the description of Sabhāparva (Sabhaparva) in Mahābhārata (Mahabharata), the Ekāsana (Ekasana) tribe dwelt in the bamboo grove located between the two mountains – Sumeru and Mandara–

On the occasion of the Rājasūya(Rajasuya) yajña(yajna) of Yudhiṣṭhira (Yudhishthira), the representatives of the Khasa tribe offered him and the other Pāṇḍava (Pandava), a gift of heaps of pipīlaka svarṇa (pipilaka swarna, gold particles as innumerable as ants), measured in Droṇa (Drona) or Droṇakalasa (Dronakalasa; a kind of container used for measuring corns).
Scholars consider the river Khotan or Hotan as identical with the ancient river Śailodā (Sailoda). The river Khotan , emerging out of the Kunlun mountain-range, flows northwards , across the desert of Tallamakan. In Chinese language, Yutian is another name of the river Khotan or Hotan.
The Ekāsana tribe, like many other tribes of Asia Minor, probably migrated to the areas adjacent to Himālaya (Himalaya; the famous mountain range) and settled there. Moti Chandra, however, has not considered this tribe as nomadic.
