The , also known as the Lamentations of Divergences, is a late 13th century short Buddhist text generally thought to have been written by Yuien, a disciple of Shinran. In the Tannishà Â, Yuien is concerned about the rising doctrinal divergences that emerged in Jà Âdo Shinshà « Buddhism after the death of their founder, so he wrote down dialogues between himself and Shinran that he could recall when his master was alive.

Further, an appendix discusses the history of the exile of Shinran and other disciples of the Pure Land movement, including his teacher Hà Ânen, from the capitol during the reign of Emperor Go-oba. Finally, a postscript, composed by Rennyo states that:
