This paper is a study about the reason why Ryochu (良忠) wrote the Ketto Jushuin Gimonsho (決答授手印疑問抄). Honen, Shoko (聖光), and subsequently Ryochu, throughout their lives held a relative, not an absolute, standpoint. The typical explanation of this standpoint is just a metaphor of two rivers and a white path (niga-byakudo 二河白道), and we must try to understand the three thoughts (sanjin 三心) through this metaphor.
