Pupil of Uttarajíva of Pagan. He went to Ceylon with his teacher, received the higher ordination there, and lived in the Mahávihára for some years. Among his works are the Kaccáyana suttaniddesa, the Sankhepavannaná, the Símálankára, the Vinayagúlhatthadípaní, the Námácáradípaní (on ethics), the Ganthisára (an anthology of texts), and the Mátukatthadípaní and Patthánaganánaya (both on Abhidhamma topics).
On Chapata's return to Burma, he brought four companions from Ceylon Ráhula, Ananda, Sívalí and Támalinda - and, with their help, he founded the Síhalasangha in Pagan, followers of the Mahávihára tradition. King Narapatisithu gave them his patronage, but extended it to other sects as well, and the Síhalasangha, therefore, remained only as one sect among several in Burma. Chapata lived in the twelfth century. Gv.64, 74; Sás.65, 74; Svd.1247 f,; Bode, 17, 18, 19.
