Pupil of Uttarajīva of Pagan. He went to Ceylon with his teacher, received the higher ordination there, and lived in the Mahāvihāra for some years. Among his works are the Kaccāyana suttaniddesa, the Sankhepavannanā, the Sīmālankāra, the Vinayagūlhatthadīpanī, the Nāmācāradīpanī (on ethics), the Ganthisāra (an anthology of texts), and the Mātukatthadīpanī and Patthānaganānaya (both on Abhidhamma topics).
On Chapata's return to Burma, he brought four companions from Ceylon Rāhula, Ananda, Sīvalī and Tāmalinda - and, with their help, he founded the Sīhalasangha in Pagan, followers of the Mahāvihāra tradition. King Narapatisithu gave them his patronage, but extended it to other sects as well, and the Sīhalasangha, therefore, remained only as one sect among several in Burma. Chapata lived in the twelfth century. Gv.64, 74; Sās.65, 74; Svd.1247 f,; Bode, 17, 18, 19.
