佛祖統紀 8.13

8.13

十祖興道尊者道邃。不知何許人。唐大歷中（代宗）來依荊溪於佛隴。洞悟幽玄無所凝滯。荊溪嘉之曰。吾子其能嗣興吾道矣。遂授以止觀輔行。師為眾開說發明深旨。聽者無不領寤。同門元皓一見師大敬服。貞元二十一年。日本國最澄遠來求法。聽講受誨晝夜不息。盡寫一宗論疏以歸。將行詣郡庭白太守。求一言為據。太守陸淳嘉其誠。即署之曰。最澄闍梨。身雖異域。性實同源。明敏之姿。道俗所敬。觀光於上國。復傳教於名賢。邃公法師。總萬法於一心。了殊塗於三觀。而最澄親承祕密。不外筌蹄。猶慮他方學者。未能信受其說。所請印記安可不從。澄既泛舸東還。指一山為天台。創一剎為傳教。化風盛播。學者日蕃。遂遙尊邃師為始祖。日本傳教實起於此（晁說之。撰明智塔銘云。荊溪傳行滿。滿傳廣修。案大宋僧傳。邃法師傳廣修。修傳物外。今依宋傳。以邃師次荊溪為正。晁氏親見明智者。不知當時何緣得此異說）。

The Tenth Patriarch, the Venerable Xingdao Daosui, was of unknown origin. During the Dali era of the Tang (under Daizong), he came to rely on Jingxi at Folong. He thoroughly penetrated the obscure and profound without impediment. Jingxi commended him, saying: 'My son, you will indeed be able to continue and revive my Way!' He then bestowed upon him the Supplementary Practices of Calming and Contemplation. The Master expounded it for the assembly, elucidating the profound meaning, and none of the listeners failed to comprehend and awaken. His fellow disciple Yuanhao respected and submitted to the Master immensely upon meeting him. In the twenty-first year of the Zhenyuan era, Saichō of Japan came from afar to seek the Dharma. He listened to the lectures and received instruction day and night without rest, copying the treatises and commentaries of the entire lineage to return home with them. When he was about to depart, he went to the prefectural office and informed the prefect, asking for a statement as evidence. The prefect Lu Chun commended his sincerity and thereupon endorsed it, writing: 'Ācārya Saichō, though from a foreign land, is truly of the same source in nature. With a bright and penetrating disposition, he is revered by both monastics and laity. Having observed the glory of our superior state, he furthermore received the teachings from renowned worthies. Dharma Master Sui unites the myriad dharmas in the one mind and understands diverse paths through the three contemplations; and Saichō personally received the secrets, not stopping at mere traps and snares. Yet fearing that scholars in other lands might not believe and accept his words, how could I not grant the seal of confirmation he requested?' Once Saichō sailed back eastward, he designated a mountain as Tiantai and founded a monastery named Dengyō. The breeze of transformation spread widely, and his students multiplied daily; thus they came to revere Master Sui from afar as their founding patriarch. The transmission of the teachings in Japan truly began with this (Chao Shuozhi, in composing the stele inscription for Mingzhi, wrote: 'Jingxi transmitted to Xingman, and Man transmitted to Guangxiu.' According to the Da Song sengshizhuan, Dharma Master Sui transmitted to Guangxiu, and Xiu transmitted to Wuwai. Now, following the Song biography, taking Master Sui as succeeding Jingxi is correct. Since Chao personally saw Mingzhi, it is unknown how this divergent account arose at that time).
