Master Sheng Yen (1930-2009) wrote Jiaoguan Gangzong Guanzhu 教觀綱宗貫註 in his 70s. In this book, Master Sheng Yen mentions the Japanese monk Daiho Shudatsu(1804-1884)'s Jiaoguan Gangzong Shiyi Huiben Jiangshu 教觀綱宗釋義會本講述. Shudatsu was an important scholar of Tendai sect in the late Edo period, who entered the Meiji period in his later years. He once taught Fahua san dabu 法華三大部. He and his teacher Echo (1780-1862) are regarded as the last great masters of the Tendai sect of modern Japan. As a master of Tendai sect in Japan, it is not surprising that Shudatsu taught and annotated the works of the patriarchs of the Tang dynasty, such as Fahua Xuanyi 法華玄 義 and Fahua Wenju Ji 法華文句記. What's more, it is a kind of display of one's own knowledge. However, what are the reasons why it is necessary to conduct research and lectures on the pre-modern Chinese monk Ouyi Zhixu (1599-1655)'s Jiaoguan Gangzong 教觀綱宗? What are the characteristics and value of Jiaoguan Gangzong Shiyi Huiben Jiangshu 教觀綱宗釋義會本講述? This article will focus on the book by Shudatsu to further explore the issue of East Asian acceptance history of Zhixu's Jiaoguan Gangzong 教觀綱宗.
