Vohra 1996, pp. 216–17 writes that Gesar is mentioned in a Khotan text, the Tibetan Li-yul-lung-bstan-pa, ("Prophecy of the Li Country") of the 9th-10th century, and Phrom long identified with a country northeast of Yarkand. Recent opinion identifies the land either with the Turkic Küūsen or the Kushan territories of Gandhāra and Udayana. Gesar may be either someone of Turkic stock or a non-Tibetan dynastic name. The Khotan king Vijaya Sangrama's consort Hu-rod-ga (Hu-rong-ga) was Phrom Gesar's daughter. The Padma-thang-yig records a Tibetan army subduing Gesar, something also mentioned in the Rygal-po'i-bka'i-than-yig ("Pronouncements concerning Kings"). Vohra, Rohit (1996).

Papas 2011, p. 268 writes that Stag-gzig, 'the mythical region of the origin of Bon-po,' was often conflated with 'Ol-mo-lung-ring, which modern scholars locate somewhere between northern Persia and Tibet's western borders.' It refers apparently... to the Persian-speaking part of Central Asia, that is, the land of the Tajiks according to Islamic sources, including present-day Tajikistan and Southern Uzbekistan, more precisely the Bukhara and the Samarkand areas. Apart from the question of the origin of Bon-po, one can perceive the name Stag-gzig/Tajik as a memory, in Tibetan culture, of its Central Asian roots.' Papas, Alexandre (2011).
