Oddiyana

Oḍḍiyāna (Skt. Oḍḍiyāna; Tibetan: ཨུ་རྒྱན་, Wylie: u rgyan Mongolian: Үржин urkhin, Odia: ଓଡ଼ିଆଣ), a small country in early medieval India, is ascribed importance in the development and dissemination of Vajrayana Buddhism. It is conventionally placed in Pakistan's Swat valley although a case can also be made for its location in the Indian state of Odisha. Later Tibetan traditions view it as a legendary heavenly place inaccessible to ordinary mortals. Padmasambhava, the 8th-century Buddhist master who was instrumental in the introduction of Buddhism to Tibet, was believed to have been born in Oddiyana.

The physical location of Oḍḍiyāna is disputed and open to conjecture. Possible locations that have been identified are:

In his argument, P. C. Bagchi states that there are two distinct series of names in Tibetan: (1) O-rgyān, U-rgyān, O-ḍi-yā-na, and (2) O-ḍi-vi-śā, with the first series connected with Indrabhūti, i.e., Oḍiyăna and Uḍḍiyāna, while the second series falls back on Oḍi and Oḍiviśa, i.e., Uḍra (Odisha) and has nothing to do with Indrabhūti. N.K. Sahu objects, however, and points out that these two sets of names are seldom distinguished in Buddhist Tantra literature, and opines that the words Oḍa, Oḍra, Uḍra, Oḍiviśa and Oḍiyāna are all used as variants of Uḍḍiyāna. In the Sādhanamālā, he further points out, Uḍḍiyāna is also spelt as Oḍrayāna while in the Kālikā Purāṇa, as indicated earlier, it is spelt either Uḍḍiyāna or Oḍra. There is also evidence, Sahu continues, that Indrabhūti is the king of Odisha rather than of the Swāt valley. The Caturāsiti-siddha-Pravṛtti, for example, mentions him as the king of Oḍiviśa while Cordier, in his Bṣtān-ḥgyur catalogue, gives sufficient indications of his being the king of Orissa. Also, in his famous work Jñānasiddhi, king Indrabhūti opens it with an invocation to Lord Jagannātha, a deity intimately associated with Odisha and with no other area of India.
