缀合敦煌文献中的6个卷子，可以完整展现《佛法东流传》的原貌。从内容来看，《佛法东流传》与智昇《续集古今佛道论衡》基本吻合；但从文章内部透露的相关信息推断，两书不可能出自智昇之手，而很可能源自释法琳《释老宗源》。《释老宗源》因收录了《汉法本内传》被“禁断”传播。智昇以续补《集古今佛道论衡》的名义，将《释老宗源》中的佛教部分辑录出，以《续集古今佛道论衡》之名顺利入藏。至于敦煌本《佛法东流传》，早在《续集古今佛道论衡》成书之前就以单本形式流传于世了。

By piecing together seven manuscripts from Dunhuang documents, an original version of The Eastward Spread of Buddhism has been reproduced. It is basically consistent in content with the Ongoing Disputes between Buddhism and Taoism by Zhi Sheng. As judged from relevant information provided by the texts, the two books could not have been written by a same author. The texts might be drawn from Fa Lin’s Origins of Taoism and Buddhism, which was forbidden because it recorded in The Dissemination of Buddhism in the Han Dynasty. However, it was included in the Tripitaka because Zhi Sheng had compiled the section on Buddhism from the Origins of Taoism and Buddhism in the name of Ongoing Disputes between Buddhism and Taoism. As for the Dunhuang version of The Eastward Spread of Buddhism, it had been circulated as a single version much earlier than the writing of Ongoing Disputes between Buddhism and Taoism.
