Rennyo.

About Rennyo

Rennyo was a descendant of Shinran and the 8th head priest of the Hongan-ji branch of Jōdo Shinshū, a major Japanese Buddhist tradition. He is known for his tireless preaching of the Shin teaching and is credited with transforming the Honganji into a major religious organization. According to Dobbins, during Rennyo's tenure, Hongan-ji temple "emerged as the premier institution of the school, and the Shinshū itself burgeoned into one of Japan's largest and most powerful schools of Buddhism." Shinshū Buddhists often refer to him as the restorer of the sect. He was also known as Shinshō-in (信証院), and posthumously Etō Daishi (慧灯大師).
