Tannisho Prologue by Yuien

Original JapaneseTranslation by Taitetsu Unno
ひそかに愚案ぐあんめぐらしてほぼ古今ここんかんがふるに、先師せんし(親鸞)の口伝くでん真信しんじんことなることをなげき、後学こうがく相続そうぞく疑惑ぎわくあることを思ふおもうに、 幸ひさいわい有縁うえん知識ちしきによらずんば、いかでか易行いぎょう一門いちもんることをんや。まったく自見じけん覚悟かくごをもって他力たりき宗旨しゅうしみだることなかれ。In reflecting upon my foolish thoughts and thinking of the past and present, I deeply regret that there are views deviating from the true entrusting (shinjin) which was taught orally by our late master, and I fear that doubts and confusions may arise among the followers who come after us. Unless we rely upon a good teacher with whom our karmic destinies are fortunately bound, how can we possibly enter the gate of effortless practice? Do not violate the fundamentals of Other Power by imposing upon it your own interpretations.
よって親鸞しんらん聖人しょうにん御物おんものがたりおもむきみみそことどむるところいささかこれをしるす。ひと同心どうしん行者ぎょうしゃ不審ふしんさんぜんがためなりと云々うんぬんThus have I [Yui-en] committed to writing some words of the late Shinran which still ring clearly in my ears. My sole purpose is to dispel the clouds of doubt in the minds of the practitioners with the same aspiration.
