The Da piluzhena chengfo jing shu （Commentary on the Vairocana-abhisam!bodhi-tantra）. 20 fasc. （T 1796.39.579a-649c）， abbr. Dainichikyo^sho 大日经疏 or Daisho 大疏， composed by Yixing 一行 in 725 CE. Commentary on the first 31 chapters （6 fasc.） of the Vairocana-abhisam!bodhi-tantra 大日经 （T 848）. The fascicle numbers of the original and the commentary correspond as follows: 1:1-8， 2:9-10， 3:19:13， 4:12-13， 5:14-17， 6:18-20. Partially based on lectures given by S/ubha^karasi?ha 善无畏 at the time of its translation. A great many Sanskrit terms and their Chinese equivalents are described in detail， and Yixing supports doctrinal points with citations from a plethora of Chinese Maha^ya^na texts -- occasionally adding insights from his experience with the Tattvasam!graha system （T 866）. These informed references to existing traditions， together with the natural authority of S/ubha^karasi?ha's comments， contributed greatly to the successful adoption of the Vairocana-abhisam!bodhi-tantra in East Asia.
（An abridged version， the Dainichikyo^ gishaku 大日经义释 （Z.36.507ff）， was circulated by Yixing's associates after his death.） Ku^kai 空海 frequently quotes Yixing's full commentary in his writings; he was the first to bring it to Japan， where sub-commentaries were written by Saisen 济暹 （T 2215）， Raiyu 赖瑜 （T 2217）， Yu^han 宥范 （T 2213）， Sho^ken 圣宪 （T 2539）， Yu^kai 宥快 （T 2218） and Donjaku 昙寂 （T 2219）; of these， the latter two are perhaps the most helpful.
