a^nanda， a cousin of S/a^kyamuni， who became one of his ten primary disciples 十大弟子. He is said to have had a perfect memory and thus was capable of recalling all of the Buddha's sermons. At the time of Buddha's death he had not yet attained enlightenment， and only achieved this following the exhortations of Ka^/syapa 迦叶， S/a^kyamuni's successor. After his enlightenment， the rest of the sam!gha allowed his recitation of the sutras. Thus all the scriptures are said to have been recorded from the mouth of a^nanda， who begins each recitation with "Thus I have heard...（如是我闻）"
