Princess Bhrikuti Devi of Licchavi, known to Tibetans as Bal-mo-bza' Khri-btsun, Bhelsa Tritsun, or simply, Khri bTsun, is traditionally considered to have been the first wife and queen of the earliest emperor of Tibet, Songtsen Gampo, and an incarnation of Tara. She was also known as "Besa", and was a princess of the Licchavi kingdom of Nepal and later the queen consort of Tibet.
Even though the historicity of Bhrikuti Devi is not certain, and no reference to her has been found among the documents discovered at Dunhuang, "there are increasing indications supporting this hypothesis." There were certainly very close relationships between Tibet and Nepal at this period and, "Such a mythological interpretation discredits in no way the historical likelihood of such a marriage...."
Many Tibetan accounts make Bhrikuti the daughter of Amshuvarma, co-ruler and successor of Śivadeva I. If this is correct, the marriage to Songtsen Gampo must have taken place sometime before 624 CE. Acharya Kirti Tulku Lobsang Tenzin, however, states that Songstän Gampo married Bhrkuti Devi, the daughter of king "Angsu Varma" or Amshuvarma of Nepal in 632.
