Genshin

Genshin (源信; 942 – July 6, 1017) was a prominent Japanese monk of the Tendai school, recognized for his significant contributions to both Tendai thought and Pure Land Buddhism.

Genshin's Ōjōyōshū was also instrumental in shaping later Japanese Pure Land figures such as Ryōnin, Hōnen, Shinran and Benchō. Genshin was therefore considered a patriarch in...
