THERAVADA AND HINAYANA
Theravada tradition is based on the set of teachings decided by the Third Council to contain the teachings of the Buddha. Shri Lanka has played a central role in preserving the Theravada scriptures and practices.
After the Third Council, the Tripitaka collection of sutras were taken to Shri Lanka. Most of these were originally in the Pali language, but some were compiled in other languages. Through the centuries however,all teachings were translated into Pali (around 35 BCE).
Initially,most ordained Sangha were known as parivrajahas (wanderers).They would assemble during the rainy season when travelling became problematic. Gradually, buildings were donated and the Sangha became more static.
