The First Council， convened at Ra^jagr!ha 王舍城 in Magadha 摩揭陀 subsequent to the passing away of S/a^kyamuni; also known as the Council of the Five Hundred （arhats） 五百结集， 五百集法， the Council of Ra^jagr!ha 王舍城结集， the Council of Ka^/syapa 迦叶结集法藏， etc. The accounts of this council vary， but the most standardized version states that the council was convened by Maha^ka^/syapa， with the intent of establishing a defined written canon for the Buddha's teachings. The two leading monks who are said to have assisted in coordinating this compilation were Upa^li 优婆离， who supervised the compilation of the vinaya collection， and a^nanda 阿难， who compiled the sutra collection.
