Rikṣa (Riksha) was one of the mountains in ancient India. In the Mahābhārata Purāṇa (Mahabharata Purana), it was mentioned as one of the Kulaparvatas of Bhāratvarṣa (Bharatvarsha). Sometimes Rikṣa (Riksha) parvata or mountain was renamed as Rikṣvāna (Rikshavana) parvata.

In the ancient books, the position of Rikṣa (Riksha) or Rikṣvāna (Rikshavana) parvata was very clearly indicated. This parvata was situated near the Vindhya mountain region. The Narmadā river was created from this parvata. In the Vanaparva of the Mahābhārata (Mahabharata), this Rikṣvāna (Rikshavana) parvata was indicated as the border of Āryavarta or North India. The remaining part is known as South India-

Ete gacchanti vahavaḥ paṇthāno Dakṣiṇāpatham.
Avantīmṛkṣavantañca samatikramya parvatam.

Based on the descriptions in the Rāmāyana (Ramayana) and the Mahābhārata (Mahabharata), the scholars point out the eastern side of the Vindhya mountain and the mountainous regions of Odisha and Chotonagpur as the ancient Rikṣa (Riksha) parvata. From this hilly regions, the Narmadā river and the Śoṇa (Sona) river were created.

In this Rikṣa (Riksha) parvata, the ancient tribes of India like Vānara (Vanara) and Rikṣa (Riksha) lived. It was mentioned in the Rāmāyana (Ramayana) that Jāṁvavāna (Jamvavana) was the inhabitant of this Rikṣa (Riksha) parvata. There was a story of Syamantakamaṇi (Syamantakamani) in the Purāṇa (Purana). In this tale, it was depicted that in search of Syamantakamaṇi (Syamantakamani), Kṛṣṇa (Krishna) came to the Rikṣa (Riksha) parvata and here he met with Jāṁvavāna (Jamvavana).

The same narrative was written in the Mahābhārata (Mahabharata). When Paraśurāma (Parsurama) was killing the kṣatriyas (kshatriyas) inconsiderately, the son of king Vidūratha (Viduratha) of the Puru clan, was secretly reared in this Rikṣa (Riksha) parvata by the Anārya (Anarya) tribe, Rikṣa (Riksha).

Though Rikṣa (Riksha) parvata was mainly known as the source of the river Narmadā (Narmada), many other small rivers were also created from this mountain. It was said in the Vāyu Purāṇa (Vayu Purana) that the rivers like Narmadā (Narmada), Śoṇa (Sona), Tamasā (Tamasa), Mandākinī (Mandakini), Daśarṇā (Dasarna), Karatoyā (Karatoya) etc. were created from this Rikṣa (Riksha) parvata.
