Aṃshuvarmā (also Anshuverma, Amshuvarm) was a monarch of the Nepali kingdom of Licchavi between 605 and 621. He is credited with opening trade routes to Tibet, though he is most famous for one of his daughters, Bhrikuti, who married a Tibetan ruler named Tsrong-tsong Gompo (King Srong Tsangampo / Srong btsan sGampo). She was instrumental in spreading China. The Chinese Buddhist monk Xuanzang, who visited India during the 7th century, described Aṃshuvarmā as a man of many talents.
An inscription by Aṃshuvarmā dated to 607 at Tistung professes the importance of the "Aryan code of conduct" (i.e. the caste system).
Chinese pilgrim Xuan Xang (Hsuan-tsang) had mentioned in his travel diary that the number of Hinayana and Mahayana Buddhist monks were more than two thousands.
An inscription of Amshuvarma has also confirmed a conspicuous presence of Bhikshuni Sangha belonging to the Mahasanghika sect
Now the question arises as to what was the Vinaya lineage of Newar Buddhist Tradition.
