The Huayan jing; Avatam!saka-su^tra. One of the most influential texts in East Asian Buddhism， of which three Chinese translations were done， all with the full title of Dafangguangfo huayanjing 大方广佛华严经. This text describes a cosmos of infinite realms upon realms， mutually containing each other. The vision expressed in this work was the foundation for the creation of a the Huayan school 华严宗 of Buddhism， which was characterized by a philosophy of interpenetration （通达、圆融）. The sutra is also well known for its detail description of the course of the course of the bodhisattva's practice through fifty-two stages. Fragmentary translation of this text probably began in the second century， and the famous "Ten Stages" 十地经 book， often treated as an individual scripture， was first translated in the third century. The first full translation was completed by Buddhabhadra 佛驮跋陀 around 420 （Avatam!saka-su^tra; 60 fascicles， T 278.9.395a-788b.）; the second translation （80 fascicles Avatam!saka-su^tra; T 279.10.1b-444c.） was completed by S/iks!a^nanda 实叉难陀 around 699; the third was completed by Prajn~a^ 般若 （40 fascicles， Gandavyu^ha; T 293.10.661a-848b） around 798.
