Tamrashatiya
The Tāmraśāṭīya (Sanskrit: ताम्रशाटीय, Tāmraśāṭīya), also called Tāmraparṇīya (Sanskrit; Pali: Tambapaṇṇiya) was one of the early schools of Buddhism and a branch of the Vibhajyavāda school based in Sri Lanka. It is thought that the Theravāda tradition has its origins in this school.
Its sutras were written mainly in Pali; and the Pali canon of Buddhism largely borrowed from this school.[1] The Tāmraśāṭīya is also known as the Southern transmission or Mahaviharavasin tradition.[1][2] This contrasts with Sarvastivada or the 'Northern transmission', which was mostly written in Sanskrit and translated into Chinese and Tibetic languages.[1]
The Tamrashatiya tradition developed into Theravada Buddhism and spread into Myanmar, Thailand, and other parts of Southeast Asia.[2]
