In one biography of Honen ("The World's Fine Things: Biography of Priest Honen") included in "Showa Shinshu Honen Shonin Zenshu" (complete works of Honen Shonin) appears: 'Word of mouth commentary on the righteous die happier than the evil' which is also found in Kudensho ("What Shinran Taught") and "Tannisho" (Lamentations).
法然の伝記の一つである『醍醐本法然上人伝記』（『昭和新修法然上人全集』所収）のなかに「善人尚以往生況悪人乎口伝有之」と、『口伝鈔』『歎異抄』と同じ文言がある。
