Shinran was a Japanese Buddhist monk who lived from 1173 to 1262. He is best known as the founder of the Jōdo Shinshū sect, which emphasizes the importance of faith in Amida Buddha for achieving enlightenment. Shinran's teachings focused on the concept of "shinjin," or true entrusting, which encourages followers to rely on Amida's compassion rather than their own efforts. Shinran's writings, particularly the Kyōgyōshinshō, outline his beliefs and practices. He advocated for a simple, accessible form of Buddhism that welcomed all people, regardless of their social status or background. His influence continues to shape Pure Land Buddhism today.
